Story telling
===========
Below is a storytelling script for each question, written in a conversational, confident, leadership-oriented tone.
You can speak this exactly in the interview — it sounds natural, senior, and impressive.
---
🎤 1. “How do you integrate a CI/CD pipeline?” — Storytelling Version
Story Script:
“When I integrate a CI/CD pipeline, I treat it like onboarding a new team member — it should be reliable, predictable, and add value from Day 1.
In one of my previous projects, we were modernising a legacy Wealth Management application. Developers were pushing code manually, deployments took hours, and production had frequent issues.
So I integrated a full CI/CD pipeline:
When developers committed code, the build automatically started
Unit tests, code quality, and security scans were triggered
Container images were packaged and stored in an artifact registry
Deployments to OpenShift were handled through GitOps using ArgoCD
Production deployments went via canary rollout based on error rates and latency
The entire process became automated end-to-end.
Earlier, a release used to take 4 hours. After CI/CD, it took 15 minutes.
So my approach is simple:
Build → Scan → Test → Package → Deploy → Observe → Rollback
All backed with automation and quality gates.”
---
🎤 2. “What are the stages of a CI/CD pipeline?” — Storytelling Version
Story Script:
“I explain pipeline stages just like a quality-controlled assembly line in a car factory.
1. Code Stage – Engineers write and review the code.
2. Integration Stage – Code is built, unit tested, and checked for quality.
3. Security Stage – SAST, SCA, container scans.
4. Delivery Stage – App is deployed to DEV/UAT automatically.
5. Governance Stage – Approvals, change management, compliance checks.
6. Production Stage – Canary or blue–green with observability gates.
7. Feedback Stage – Metrics, SLOs, DORA metrics.
Just like each step in a factory ensures no faulty part moves forward, each pipeline stage ensures no faulty code goes to production.”
---
🎤 3. “What challenges did you face in pipelines?” — Storytelling Version
Story Script:
“One major challenge I faced was inconsistent environments.
The pipeline passed in Jenkins, but failed in OpenShift due to different versions of runtime libraries.
Another challenge was long execution times — our test suite took 45 minutes, and developers were waiting idle.
Security scans also slowed things down; they used to run only at the end, leading to last-minute security blockers.
Also, we faced configuration drift — what was defined in Git didn’t match what was running in production.
These real-world issues taught me that pipelines need as much care as production systems.”
---
🎤 4. “How did you improve your pipelines?” — Storytelling Version
Story Script:
“I improved our pipelines by introducing three transformative changes.
First, I created reusable pipeline templates — any new team could adopt CI/CD in hours instead of days.
Second, I parallelized tasks. Earlier, unit tests, linting, and security scans were sequential; I made them run together. Build time reduced by more than half.
Third, I introduced GitOps so deployments were traceable, auditable, and rollback-ready.
As a result, our deployment frequency increased, failures dropped, and teams became more confident.”
---
🎤 5. “What steps do you follow to decommission an application?” — Storytelling Version
Story Script:
“I follow a structured 7-step decommission framework.
Recently, we had to retire a legacy mutual funds reporting system. First, I validated ownership and mapped dependencies — we discovered several hidden AutoSys jobs and two BI dashboards relying on it.
Second, we performed a risk assessment and agreed on a cutover plan with business, security, and architecture.
Third, we archived all historical data as per retention policy.
Fourth, we disabled traffic, removed DNS, deleted OpenShift deployments, databases, pipelines, and rotated certificates.
Finally, we updated CMDB and documented cost savings.
This structured approach ensured zero customer impact and full compliance.”
---
🎤 6. “Explain 2–3 complex scenarios where your contribution mattered.” — Storytelling Version
---
Scenario 1 — Kubernetes Probe Misconfiguration Causing DB Outage
“Once, we had an outage because a liveness probe was triggering a heavy DB call every 30 seconds.
Pods kept restarting… the DB connection pool got exhausted… customers couldn’t log in.
When I joined the bridge:
I identified the probe design as the root cause
Created a lightweight /healthz endpoint
Tuned readiness and liveness probes
Added connection pooling limits
Documented the best practice for all teams
Post fix — zero incidents. This became a bank-wide learning.”
---
Scenario 2 — Kafka MTLS Certificate Chain Issue
“In another case, after a certificate rotation, Kafka producers couldn’t talk to brokers. TLS handshake failed and message lag shot up.
I detected that the intermediate CA was missing in the truststore.
I automated certificate chain validation in CI and set up early expiry alerts.
What was a recurring problem turned into a zero-incident domain for the entire year.”
---
Scenario 3 — Ansible Zero-Downtime Patching
“We were having 2 hours downtime every month during patching for 150 apps.
I built a rolling-patching pipeline using Ansible:
Cordon a node
Drain workloads
Patch
Health-check
Move to next node
We achieved 100% zero downtime.
Teams kept their SLAs intact and business loved it.”
---
🎤 7. “What decisions did you take that gave long-term benefits?” — Storytelling Version
Story Script:
“One long-term decision was moving the whole organisation to GitOps.
Before GitOps, configurations drifted and debugging took forever.
After GitOps, everything was traceable and consistent.
Another decision was automating certificate lifecycle — earlier, certificate expiry was a repeating Sev1 issue. After automation, we never had another TLS outage.
Finally, I enforced an SRE Production Readiness Checklist — covering probes, autoscaling, monitoring, dashboards, SLOs, and alerting.
This single framework reduced Sev1 incidents by 40%.”
---
🎤 8. Lloyds 5 Values — Storytelling Version
---
1. We Put Customers First — Story Storytelling
“One evening, a high-risk release was planned.
My team was ready, but monitoring showed latency spikes.
If we deployed, customers might face login failures.
I took the call to postpone the release, even though everything was prepared.
Yes, it delayed our timeline, but it protected customer experience.
This is what putting customers first means to me.”
---
2. Be Bold — Storytelling
“When teams hesitated to adopt GitOps, I sensed fear of the unknown.
I created a small pilot with one team, proved deployment time reduction, and showed success with real data.
Taking that bold step triggered a cultural shift — within three months, four squads adopted GitOps.”
---
3. Inclusive — Storytelling
“I noticed junior engineers struggling with Kubernetes YAMLs.
Instead of leaving them behind, I made reusable templates and conducted hands-on sessions.
Suddenly everyone — junior, senior, QA — could contribute to deployments.
That’s inclusion in action: making everyone part of the journey.”
---
4. Trust Driven — Storytelling
“We once had a production outage because of a manual config change.
Instead of blaming the engineer, I conducted a blameless postmortem — focusing on the process, not the person.
We improved automation, added guardrails, and the engineer felt supported, not punished.
Trust grows when people feel safe.”
---
5. Put Community Together — Storytelling
“In my previous organisation, platform teams worked in silos — Kafka, DB, SRE, OpenShift.
During incidents, alignment was painful.
I created a weekly ‘Production Readiness Community’ where all teams shared learnings and best practices.
Within weeks, coordination became smooth, incidents reduced, and we acted like one community — not isolated islands.”

Below is a complete, polished, interview-ready script for all the questions Lloyds asked you today.
These answers are structured, leadership-oriented, SRE-centric, and aligned to Lloyds’ culture and values.
---
✅ 1. How do you integrate a CI/CD pipeline?
Answer (Manager-Level):
“I integrate a CI/CD pipeline by treating it as a product—with clear stages, automated governance, security gates, and measurable outcomes. My approach is:**
1. Requirements & Architecture
Understand branching strategy (GitFlow / trunk-based).
Define environments (dev → test → UAT → prod).
Identify required gates (security scans, approvals, change management).
2. Build Pipeline Integration (CI)
Source code triggers build (Git webhook).
Run:
Unit tests
Static code analysis (SonarQube)
Dependency scanning (Snyk)
Container scanning (Trivy / Aqua)
3. Packaging & Artifact Management
Build container images
Store in artifact registry (ECR, JFrog, Nexus)
4. Deployment Pipeline Integration (CD)
Deploy to lower environments using:
ArgoCD / Tekton / Jenkins / Azure DevOps
Apply GitOps methodology for auditability.
5. Observability & Rollback
Implement logging, metrics, traces
Canary / blue–green deployments
Automated rollback if SLO degradation
6. Governance
Align with change management, security, and SRE production readiness.
---
✅ 2. What are different stages of a CI/CD pipeline?
Use this crisp framework:
1. Code Stage
Branching
Peer review
Pre-commit checks
2. Continuous Integration Stage
Build
Unit tests
Linting
Static code analysis
3. Security Stage
SAST
SCA / license scanning
Container scanning
Secrets detection
4. Continuous Delivery Stage
Deploy to DEV / QA
Integration testing
E2E validation
5. Approvals & Governance
Change management
Security sign-off
SRE production readiness checklist
6. Production Deployment
Canary / blue-green
Observability validation
Automated rollback
7. Continuous Feedback
Metrics
DORA KPIs
Post-deployment review
---
✅ 3. What challenges have you faced in pipelines?
Give real-world SRE challenges:
Challenge 1: Pipeline failures due to inconsistent environments
Example: Jenkins agent versions differed → builds succeeded in some nodes but failed in others.
Challenge 2: Long pipeline execution times
Testing stage took 45 minutes → delayed deployments.
Challenge 3: Security delays
SAST scans took 20 minutes → developers bypassed security gates.
Challenge 4: Drift between Git manifests & actual cluster state
ArgoCD out of sync → wrong configurations in production.
Challenge 5: Secrets accidentally committed
Sensitive configs leaked → required secret scanning and vault integration.
---
✅ 4. How did you improve the pipelines?
Improvement 1: Standardized reusable pipeline templates
Common YAML templates for all teams
Reduced onboarding time by 40%
Improvement 2: Introduced parallel execution
Unit tests + static analysis + scans ran in parallel
Reduced build time from 45 → 18 minutes
Improvement 3: Shift-left security
Pre-commit SAST scans
Secrets scanning hooks
Prevented security delays later
Improvement 4: Introduced GitOps
ArgoCD-based automated deployments
No manual interventions
Eliminated configuration drift
Improvement 5: End-to-end observability gates
Added quality gates based on:
Latency
Error rate
Resource usage
Automated rollback enabled
---
✅ 5. What steps do you follow to decommission any asset/application? (Enterprise-grade answer)
Use a 7-step decommission framework:
Step 1: Identify & Validate
Inventory CMDB
Ownership confirmation
Understand dependencies (API, DB, downstream jobs)
Step 2: Risk Assessment
Impact analysis
Compliance checks
Data retention requirements
Step 3: Communication & Approvals
Notify stakeholders
Get sign-off from:
Product owner

Stop CRON/AutoSys jobs
Step 5: Data Archival
Backup DB
Move logs to long-term storage
Step 6: Infra Decommission
Delete:
Kubernetes deployments
VMs
Databases
Certificates
Secrets
Pipelines
Storage volumes
Service accounts
Step 7: Audit & CMDB Update
Update CMDB
Cost saving documented
Final audit closure

=================================
How do you establish the trust and make team comfortable
Here is a perfect storytelling leadership answer that will impress Lloyds, especially because one of their core values is “We are trust-driven.”
---
🎤 How do you establish trust and make your team comfortable?
⭐ Storytelling, senior-leader, people-first answer
Story Script:
“I build trust the same way I build reliable systems — with consistency, transparency, and psychological safety.
One example from my previous team:
When I joined as a manager, the team had just come out of a stressful production incident where a junior engineer was blamed publicly for a configuration mistake.
Morale was low, and people were afraid to take ownership.
I knew trust would not come through policies — it had to come through behaviors.
So I started with three simple actions:
1. I made the environment psychologically safe
In the very next incident, instead of asking ‘Who did this?’, I asked:
‘What in the process allowed this issue to happen?’
People immediately felt safe to speak.
I made it clear:
Mistakes are learning points, not weapons.
2. I became fully transparent
Every week, I held a short session where I shared
what decisions were being made
why we were doing certain changes
what risks we were facing
how we could improve reliability
Teams felt included, not dictated to.
3. I showed trust before asking for trust
I started delegating real ownership —
like letting a mid-level engineer lead a production change with me shadowing quietly in the background.
When people see that you trust them, they rise to the occasion.
Slowly, the culture shifted.
Engineers who were silent earlier started speaking confidently.
People began volunteering for complex tasks.
Most importantly, they trusted one another — not just me.
And when the next major incident occurred, the team handled it collaboratively, calmly, and without fear.
To me, that’s how trust is built:
By showing respect, giving transparency, empowering people, and consistently standing by them especially during failures.
That’s how you transform a group of individuals into a strong, comfortable, high-performing team.”
---
⭐ Quick punchline (use in interview if needed)
“Trust is not built during the good days — it’s built during failures.
If the team sees you stand by them in tough moments, they will run with you during transformations.”
