Rakuten Software Engineer interview questions

Interview process for Java Developer started with 2 telephonic and 1 Skype Round . Both these rounds had Core Java and Data Structure Questions . Having cleared them ,I was called for F2F interview at the Rakuten Office located in WTC ,Rajajinagar . There gave 2 more technical interviews with focus on Core Java ,Design Patterns and Problem Solving . Having successfully crossed these rounds was told to appear for CTO round via Skype . CTO round was pretty smooth . Whole process looked very organized and I was all pumped up to join the Company. Overall rating of this company over Glassdoor is below 3 (2.8) but still I thought of giving it a shot and was expecting offer to be rolled out sooner . Alas ,wait ,wait and wait . No communication from HR team for a week ,then I sent a gentle query about status . Surprisingly they didn't tell me Yes /No ,they kept me awaited citing multiple reasons like the hiring manager is traveling ,we Haven't yet got feedback ,blah blah . After 15 days of CTO round ,I finally asked rigidly about the status ,then got a naïve reply that the position has gone ON HOLD . Frustrated and dejected ,I simply replied - Thanks . Lesson Learnt - Don't waste time even interviewing here ,let alone joining . No ,not at all a good place
