Mphasis Software Engineer interview: Python rounds then client SRE and CI/CD
My process had a focused sequence of rounds. First, I had a technical interview with Python questions ranging from basic to advanced, and I cleared it. A second Python-focused round followed the same basic-to-advanced pattern, and I cleared that one too. The client round was completely different. It did not include Python questions. Instead, the client focused on site reliability concepts and CI/…
Read full experienceMphasis Software Engineer interview: background verification followed by rejection
I had a client-side interview and moved into background verification the next day. A few days later, the consulting firm told me that my profile had been rejected. That was disappointing because I had already cleared a stage that suggested progress. By the time I learned the decision, there was little room for clarification, only the message that I was not moving forward. I never received an offe…

Be Prepared for Strict Vetting and ID Verification
Mphasis interviewers are highly vigilant about security and candidate identity. You will be required to show a valid, government-issued photo ID on camera at the start of your virtual interviews. Ensure your camera is high-resolution, your workspace is quiet, and you are prepared for a strictly proctored environment.
Practice Coding Without an IDE
Some virtual technical rounds are conducted over platforms where you may be asked to write code in a plain text editor (like Notepad or a basic shared screen) without auto-complete, syntax highlighting, or online search access. Practice writing complete, syntactically correct code on paper or in a basic text editor to build confidence.
Master Your Resume Projects
Do not list any technology or project on your resume that you cannot explain in depth. Interviewers will drill down into your project architecture, database design, and your specific individual contributions. Be ready to explain the "why" behind every technical decision you made.
Understand the Client-Facing Context
Because Mphasis operates as an IT services provider, many software engineering roles are tied directly to specific client accounts. If you advance to a client round, research the client’s industry (e.g., banking or logistics) and tailor your technical answers to show how your skills solve their specific business challenges.

One customer endpoint stalls deliveries to every other destination
The egress service delivers about 1.5k webhooks/second across 40,000 destinations, with a per-destination concurrency cap of 4 and a 10-second connect-plus-read timeout. Throughput falls to 300/second, queue depth climbs, and p99 delivery latency for unaffected destinations goes from 200 ms to minutes, while the error rate barely moves. One tenant holds 900 destination rows whose URLs share a hostname that now answers in 9.5 seconds. Explain the mechanism with the arithmetic, then give the containment in the order you would apply it.
Approach
- Look at saturation before errors. A flat error rate with collapsing throughput says nothing is failing, things are waiting, so the first signal to pull is in-flight request count or pool wait time rather than the error counter. This is the distinction that decides the whole investigation.
- Group in-flight work by resolved host, not by destination id. The cap is keyed per destination row, so 900 rows sharing one hostname buy 3,600 concurrent slots against a single host, each held for 9.5 seconds. The bulkhead was never a bulkhead for that host, and grouping by the wrong dimension is why the dashboard looked healthy.
- Do the arithmetic in both directions. Required concurrency is arrival rate times latency, so 1.5k/second at 200 ms needs about 300 in flight, which is entirely consumed by 3,600 slow slots; conversely whatever concurrency is left sustains rate equals concurrency divided by 9.5 seconds, which is the 300/second you are seeing. Matching both numbers is what promotes this from a plausible story to the mechanism.
- Explain why the circuit breaker never helped. It opens on consecutive failures, and a 9.5-second response inside a 10-second timeout is a success. Slow is not failing, so an error-rate breaker cannot see this; you need a slow-call ratio, a deadline propagated from the caller's remaining budget, or a concurrency limiter.
Follow-up
- The host recovers to 80 ms. How long does the queue take to drain, and what does the drain do to the recovered host?
- Where should the 10-second timeout number actually come from?
