Three technical round - first tele call around ML ,SQL and business problem. second and third round onsite. second was around python and spark. third round discussion on machine learning and question around that. Now comes to HR round, they deferred my role and magic happened when hr offered me ctc less than what i earlier had. i asked this logic of wasting of time and such offering. she didnt had any reason. such a waste of time though initially i told my expectation.
