FDM Group Java Software Developer interview questions

After a brief phone interview, I was asked to come out to their NYC office for assessment. The assessment day consisted of brief presentation about FDM, in-person assessment test, and interview with HR and Tech Instructor. There wasn't anything particularly hard about the interview; everything was straight forward. Had to decline the offer after not being able to commit for 2-years on company (this happened after I was offered a position)

1. Assessment day at FDM group's office in NY. Assessment day comprised of 3 tests - Math, Set theory, Programming(you don't need to any programming language , just based on pseudo codes, tell what the output will be. After this there were 3 interviews ( 5 mins each) in round robin style , mostly behavioral questions , resume and basics of Java. 2. Next day they emailed me that I have passed all the tests and interviews and they made travel arrangements for client in Virginia. 3. Interview was supposed to start at 1:30 but started at 2:30 PM. There were 16 candidates who were called for the interview. There were 4 interviews each of 10 mins with a team having two members in round robin manner. round 1 - math problem( algebra) round 2- behavioral questions round 3 - questions from resume round 4 - questions from resume not related to job order of the rounds was different for every one. 4. Since interview started late, many of us missed next 2 trains and we paid for the rescheduling. The train broke down in the middle of nowhere and I reached Penn Station at 3 AM instead of 9 PM. 5. I emailed the person who arranged for travel regarding reimbursement of cabs and food( 5 hours travel one way no food was provided, and 3 hour of interview), she never replied to even clarify company's policy. That meant - Once interview is done and you are not selected we don't care who you are.
