FreshWorks On-campus Interview Experience for Software Developer
I belong to Sastra University, Thanjavur. The first round can be written from our rooms/home itself.They gave 4 coding questions. I attempted all of them and passed all the test cases.The questions were medium to tough and was given only 75 min for the test.So time management is important. Of course, Google and our friends help us in this round. All of our friends were not given same set of questions.Out of 350 students, 87 students were selected for the next round.
In this round, the shortlisted students were given a problem statement each for front end and back end.We have to select one of them or we can do both.They gave less than 12-15 hours for this round.We have to be a bit fast in this round. Out of 87, 47 students were shortlisted.
This is the first technical F2F interview.There were 15 panels.Each of us were assigned a panel. He asked me mostly on data structures.
Before asking the questions, he asked me to introduce myself and explain about my projects.
