1st round was on basics of ML, DL and writing python code.
2nd round was with CTO, more discussion on what projects have you worked with and past experience, talks about ML, DL, scenario based questions.
3rd round was on ML questions, with scenario based questions on how to approach the problem.
4th and final round was with CEO which was really the worst experience ever. He joined 10 minutes late and then kept on interrupting. He just sounded very over confident, lacking basic epathy, no wonder the reviews people have dropped are correct. I seriously pity for the employees working there. Worst CEO ever, TBH I’ve interviewed with big companies and big CEOs but this was the worst. Imagine spending 4-5 rounds and then having the last round with someone not wanting to listen. Finally no one is here to listen to your preachings. Never interview with this company.
