Resume shortlist and then interview. Dont remember if there was a test before interview sice it is long back. Anyway they did not called every one for the interview. they stopped the process in between and went without giving offer to any one. so Ididnt had a chance to attend the interview at all. they just came to the campus and went back with out taking any one from the department.Maybe due to the economic issues at that time due to covid break out.
