30 mins screening interview, including introducing my previous flutter working experience. All the questions are about Flutter, all the questions are basic level. The interviewer is really nice. but I didn't get the offer.

I had applied online.Initially I had a phone call with the manager where he asked me about the technologies they use at the company and what I've been doing at my current company.This was followed by a Hackerrank coding challenge.The next round was a skype interview with an engineer there.It was an hour of collabedit coding challenge.I was then invited for an onsite interview to Austin,TX.They had 5 round mix of technical and hr type of rounds.
