IQLECT Applications Developer interview questions

I applied to the job posting through online website and got call from HR. Later scheduled interview. First round was paper based coding. Easy 2 programming questions and I did both. Later second round was F2F based on the previous round and I was told to optimize the code what I had written earlier. I was able to do that with little help. Third round was to more of discussion about job role and little technical questions. Finally a small round with CEO. It was a general discussion round about my interest s and technical stuff. And got the offer letter on the very next day.
