It can cause overfitting problem. Model with a lot of layers will train on different set of layers to enough information, which can be sensitive to noise. Then it can cause computational time to increase and operational costs.

I led a project to implement a new feature in our loan processing system aimed at reducing API latency for faster loan approvals. Midway, I encountered data inconsistencies and latency issues caused by schema mismatches between the new API and our backend services. To resolve this, I optimized the data schema mapping, streamlined query performance, and introduced Redis caching for frequently accessed data, which significantly reduced the API call frequency and improved response times.

I also collaborated with QA to parallelize testing, allowing us to catch issues early. By continuously optimizing our microservices with adjustments to load balancing and asynchronous data processing, we increased processing speeds by 20%. While the deadline was slightly extended, our enhancements directly improved loan approval times and were a solid technical win for both the team and the user experience.

Question: Tell me about a time when you assisted a colleague in his work. What was the result?

Answer:

Sure. I really enjoy helping others on the team, especially when they’re stuck and not sure how to move forward.

S – Situation:
Once, someone on a neighboring team was struggling with a production issue for a few days. I noticed that he seemed frustrated and wanted help, but didn’t quite know how to ask.

T – Task:
After finishing my work early one day, I proactively messaged him on Teams and offered support. He was happy, but mentioned he wasn’t even sure how to describe the problem clearly.

A – Action:
So I sat down with him and tried to understand the issue. He told me that after one of his code changes went live, a dropdown component in our shared UI broke — its layout was completely messed up, even though his change didn’t touch that component directly.
I helped him debug the issue step by step. After ruling out rendering or layout bugs, I noticed the problem was actually due to a CSS variable conflict — the styles weren’t properly isolated, which caused unexpected overrides.
Together, we fixed the CSS scoping issue and verified the dropdown worked as expected.

R – Result:
The bug was resolved and the fix was shared with the wider team via email, to prevent similar issues in the future. My teammate was really grateful, and after that, our collaboration improved significantly.
