IBM Applications Developer interview questions

Got a call from Hr for interview. I before the interview I had to complete two tests each was around for 30 min. Interview location was IBM Yerwada Pune. I reached there at around 10 am. It was the worst experience I have ever had. Next round was online hackerrank test with duration 90 min. There were around 40 candidates waiting for test and only 5 machines available. After 3 pm I got chance for the test. So I that process took around 6.5 hrs. Interview management was very bad. Unavailability of machine is the worst part.
