Tech Mahindra Sen Software Engineer interview questions

they are asking basic questions and some scenario based question. Also they are checking employee communication skill. Interview process tooks too much time. I got offer after 1.5 months

1. Initial telephonic round with basic questions on azure, OOPs and SQL Server 2. HR told to send scan copy of all documents(degreee certificate, employeer's letter,reference,etc) 3. Deep technical round Interview was somewhat wierd with no proper response from HR. You don't get confirmation mail once interview is scheduled, although I asked for it. Interview started 30 mins late after reminder to HR.Interviewer were not so friendly.
