I applied through a recruiter. The process took 2 weeks. I interviewed at OpenBet (Melbourne) in Mar 2018
Interview
phone interview, then coding test, then another phone interview, and final the face to face 2 hour interview with the tech lead and development manager.
1st round phone interview just get basic info, like skills and experience.
online coding test, 5 questions need to be finished in one hour. a little bit rush. but not that difficult.
then the phone interview with one senior developer, asking a lot technical question. linux, java core, thread, mysql. etc
final round, face to face, this is the most difficult part. paper based question on java and mysql. data structure and algorithm related. need to improve the solution after your after solution.
overall, difficult interview. and very good working environment and very nice and friendly people. I love to work there so much. But I didn't make it through.
One test online. One interview call (1h) . One interview face to face (2h 30m). During the test online, it was necessary to program in HackerRank. During the phone call, you have to reply to some easy questions. During the interview face to face, you have to program different algorithms and solve some problems.
