There were two round of interviews. Both were technical. 1st interview was of approx 30-40 mins, where the interviewer checked my basic flutter knowledge. And I was able to answer most of the questions. That day only in the evening I had 2nd round with the project manager. He gave me two DSA questions about list in dart. I solved both the questions, and he asked me some advanced concepts of flutter. I answered few of them also. But, he didn't selected me and I don't know why there was no feedback given. Atleast these companies should give a feedback,as our time is also precious.
