Schneider Electric interview questions

Submitted my resume to the company at a career fair. Was contacted a few months later about three positions. Did a phone screen for two and was brought in for a final round in-person interview for one position. Had five 45-minute interviews in a row which was exhausting, the first one being a lunch interview with two younger employees and the next four being with managers. Interviews were casual conversations about my past experience and career goals, and many went over 45 minutes. However, they flew me out at 4 AM the same day as all of these interviews and flew me home on the same day, so I was extremely burnt out since the flight was 3 hours one way. Also, the HR recruiter calls me constantly which is a bit annoying.

2 rounds of interview. First there will be aptitude test kind of round. After this you will have one to one, They will take some time between aptitude round and final round. Final round will be mostly java questions. Study from websites like java revisited. If you have minimum 6 months of java coding experience you wil be fine.
