Interview was of three rounds. First, was an online test on HackerEarth. The link didn't work for some reason, so they sent me the test in an email and I submitted the solution in reply. The programming test had three questions, two were easy testing java understanding and one was moderately difficult. The second round was a Skype interview with one of their project architects. Interviewer seemed to be a kind person, he went on to have a informal chat about what the project is, discussed about my previous projects, and asked me what I expected to gain from this opportunity. Thereafter, he asked me to grab a piece of paper and a pen and went onto ask few java based programming questions. These questions were of varying difficulty levels, few were fairly easy whereas few were difficult. Thereafter, I didn't hear back from them, but if I had, they'd taken a cultural fitment test. Overall, the process was pretty good.
