Worst interview experience I ever had in my professional life.

• Applied through employee referral, got 2 first rounds as online coding/MCQ rounds.
• After this, went through 3 subsequent interviews (you can't proceed unless you qualify the previous one). The first 2 were technical, and the final round was HR, just asking normal questions. I was confident to get in, and even my referrer congratulated me that I am in.
• This whole process took almost more than 1 month, after which the most troubling thing happened. They ghosted me for 3 weeks after the final round, with no communication at all.
• Then suddenly, their HR member called me asking for details on my name, visa, and other stuff. I said, "Okay," thinking it must be related to an offer letter.
• After 3 more days, the most bewildering thing happened, which I have never experienced in my whole life. Here I was, expecting an offer letter from them, and they replied that they wouldn't be hiring me, without any reason.
• I was extremely shocked since all the interviews were over with positive feedback from all interviewers. Now they suddenly, randomly, just decided to reject me. After I mailed them, they said it was an "internal HR manager" discussion (who had no idea about my interviews at all). I wonder on what grounds did they make their decision.

All in all, they wasted more than 2 months, took 5 rounds, and wasted everyone's effort involved in the process, including me and the interviewers. They finally rejected me without any reason, citing an internal HR manager's discussion.

This was my worst experience yet, not only interview-related but overall as well. My whole effort and time were wasted over these last 2 months. I wouldn't wish the experience I had even on my worst enemy.

Sincere advice: Don't apply at Rakuten. DON'T, even if you are desperate. You can qualify through all the rounds with flying colors and still get a hard, cold rejection instead of an offer letter in the end.
