I applied through college or university. The process took 1 day. I interviewed at Altair Engineering (Kharagpur, West Bengal) in Dec 2016
Interview
interview consisted of 2 rounds nothing such as HR and technical. Interviewers are from technical side. It was my first interview and interviewers were very friendly and asked about my projects. The will make sure that you will not leave company for your higher studies just search for some reason in your resume for not going for further studies. Just be thorough with your resume and that will suffice.
