The process took 3+ weeks. The first round was a skill test in github, pretty easy. Once I cleared that I had 3 in-person interviews. First one was with front end lead, the next one with producer and the last one with front end manager. The in-person interviews were all about how passionate you are for their product. Not for the sake of this post, I was and I am still actually really passionate about their product. I used their app, bought and sold items to know about its working. I also gave them various suggestions and ideas to improve the app and it's reach. I would not take pains to think of suggestions to improve the app if I was not passionate enough. Honestly I don't know what else I had to show to prove them that I was passionate. Like seriously should I take a picture of me kissing the app and show them I'm passionate about the app ? It really got me frustrated because the reason they told was that I was not passionate about the app. Well if you want to reject a candidate, at least have the courtesy of telling the real reason and don't just cook up a reason to reject. Even now I still love the app and the cause it promotes. I was really eager to work on it, but I seriously have lost the respect for the interview team or whoever was responsible for making such poor decisions. I don't think it is my loss; they really lost someone who was really passionate about the app.

Do not apply to Mercari. It is a huge waste of time. Maybe they're nice to work for, I don't know. But unless they invite you directly to an interview, I would strongly recommend against applying. After applying through their website, I was asked to complete a 2 hour Hackerrank test. After that, without any feedback on the skill test, they sent me a github repository with the task to write a semi-functioning app. They estimated it should take 8-10 hours, or even longer, for good results. I spent 12 hours on the app, totalling 14 hours in skill tests. Then I was rejected. Without any explanation. Mercari does not respect an applicant's time at all. After spending that amount of time, it would be common decency to at least give a reason for a rejection. In fact, I had expected to discuss my code (about 1000 lines) with an interviewer. But no, not even a single line of feedback was given. Do not apply to Mercari.
