Tech Mahindra Senior Software Engineer Java interview questions

There were two technical and one managerial round. Interviews process is good but they take a long time to release the offer letter to you. Interview was moderately difficult but we just need to be patient for the offer letter.

I appeared this interview in person and was asked to dressed completely formal and to be at the location for interview. When I reached the location, the interviewer himself was working from home. And took my interview with a poor internet connection. And shared his laptop giving control to me to operate/use IntelliJ remotely. Which was lagging badly, and struggled to type anything hardly.
