InMobi Senior Software Engineer - UI interview questions

I am having 3+ years of experience and I recently attended an interview with Inmobi. The interview process was quite good and in the first round of interviews, I was asked to develop a google search UI using React. It happened with BarRaiser Team. The second round was with someone from the Inmobi team itself. The interviewer seems to be cool and explained the question in a clear way. But unfortunately, I couldn't solve the problem as I was mind blocked by a few personal issues.
