CoinSwitch Software Engineer 2 interview questions

Interview experience was very bad. 1.Interviewer joined late and that lost time was not given to me in the end. 2.interviewer has not greeted properly. 3. In ds question, i thought of an approach and started discussing with interviewer. But interviewer did not listen completely and told to write code . I thought may be interviewer is satisfied with the code. But at later stage, I found out that approach was not right. If interviewer has listened properly while I was explaining the approach in starting , this situation would not have happened. 4. Zero hints provided by interviewer. 5. There was no involvement by interviewer in listening, checking code and other things. 6. In last, interviewer didn't give me chance to ask question related to company
