Rakuten Senior Software Engineer Java interview questions

I was contacted by the recruitment team. The first two round were technical telephonic rounds. The questions covered core java basics, data structures, RestAPI implementations. Then they informed I have cleared and asked to come for an F2F. I went to WTC office of Rakuten, first round was again technical, where I was asked to solve an array rotation on paper, then some scenario based question. The next round was techno managerial round where they asked about caching techniques, logging and all. They informed I have cleared all the rounds and next day asked me to share all the previous company offer and salary documents and asked my convenient time for a Skype HR interview. Then there was no reply, when i called back they tols the position is on hold now. I attended the interview on Tuesday, they took my documents on Wednesday 12pm and by Wednesday 2pm position went on hold. Such a waste of time. I truly advice please stay away from this people. They conduct interviews just to waste our time.
