WNS Data Analyst Interview Questions
& Process

So, for the technical interview, we've got two rounds lined up, then after that, an HR round. The tech rounds are all about diving into your projects, touching on Python basics like strings and list comprehensions, diving into machine learning fundamentals, how to optimize models, and of course, SQL, plus some scenario-based questions.

This company is one of the worst I’ve ever interviewed at. They conducted three technical rounds, and in the end, they ghosted me. When you ask about the results, they ignore you as if you don’t exist. Even if they do reply, all you’ll get is a response like, "Sorry, we’ve closed hiring for this role," or "The role has been frozen." Am I stupid for giving interviews back-to-back? Not only that, they have egoistic employees in their company—employees who don’t even have IT degrees but are sitting in IT department roles, asking questions to which they don’t even know the answers. Why??? I gave six technical rounds in this company and received feedback like, "Oh, we are sorry, you are not technically qualified for this role." Are you kidding me??? Their IT department has the worst employees. Please don’t waste your time on this company—they will mentally exhaust and exploit you as a candidate.

I had a really bad experience with this company. I communicated my salary expectations to HR upfront. After I completed all the interviews, they told me they couldn't meet my expected salary. It felt like a waste of my time since they didn't have the budget. It's a terrible company with poor management.
