First, a technical round consisting of 3 coding question from moderate to hard level. Then, three round of technical interviews, first was quite easier then other two. They mainly targets for OOPS concepts, understanding in DMBS ans OS, and basic DS was asked, in my case interviewer asked me implementation of stack using linked list. Next round of interview, level of question was a bit higher than the previous one. A prefix sum coding question, SQL queries and OOPS concepts, and brief intro about my project. Another round of interview, it was like both tech and HR.
