Whole process consists of an online assessment followed by three interviews(2 technical and 1 HR+technical). Online Assessment consist of 3 questions. First question was a simple one in which we have to use a simple for loop. I solved second question using priority queue(It was kind of m discount coupons question in which we have to minimize total cost). Third question was a bit hard than previous two.(I can't remember the exact question). I was able to solve two questions completely and in third one I was able to pass 9/10 test cases.
