Posist came to our college( one in IPU-GTBIT). It was a 2-day process. The first day had 2 rounds which were elimination rounds. 1st round was an MCQ + self-introduction round where MCQs where on C, C++, DBMS and time complexities. It also included a section where one had to write about their projects and submit GitHub links and also were asked to explain them in brief.
The shortlisted students were moved to the 2nd round( I was one of those) where there was a 3 hr coding test. There was one question that was to be completed which used the concepts of trees, linked lists, hashing, and of course one's problem-solving skills. There was no language barrier and one was even free to add their own creativity and add UI to the solution.
After this, the shortlisted students went to the interview rounds. There were 2 rounds, one technical and one HR.
