I applied through a recruiter. The process took 1+ week. I interviewed at Tech Mahindra (Calcutta) in Jul 2021
Interview
I have applied through LinkedIn post in July 2021. I am a fresher from non teaching background but have the knowledge and the zeal to learn.There are Two technical rounds are followed for the Selection procedure. In the First round they send one image consists of four tables and asked about some SQL queries. After Clearing that round HR have no idea when will be the Second round will be conducted. After 2 weeks 2nd round will take place.
Before that I ask the HR about Job Description but she didn't have any knowledge about it. Just like some useless HR.
2nd round is consist on SQL and ML. A person from the panel ask unnecessary SQL questions to me and try to grill my non technical background inspite he is from commerce background and handling RPA, DATA STRUCTURE, MACHINE LEARNING ALGORITHM ALL OF IT so it is quite obvious that he doesn't have proper knowledge in any specific domains. But I have answered all the questions from ML. Inspite of that they will not provide any offer.
If you are taking fresher then you have to train him/her and that is the reason of less salary is offered to them.
If TECH MAHINDRA guys want ready guys then please don't waste time time of any fresher.
