EclecticIQ Software Engineer interview questions

I applied via employee referral, then i recieved a introductory phone call from the respected manager about the interview process, and he brief about company's product. Overall interview experience was so good and smooth. From Date of Apply to last round, it all the process finished around in one month. the best part was that they asked me about my preferred date and time slots, and there was about one week gap between each round of interview, which give enough time to prepare.
