GoKwik Software Developer (Backend Node Js) interview questions

There were a total of three rounds. In the first round, I was given a simple question of finding the second minimum element in an array using a single for loop. After that, I was asked about concepts of javascript such as the event loop, hoisting, etc. The questions were interesting. At the end of the first interview, I was asked a few simple questions related to AWS, as my role had a prerequisite of AWS. The second round was not a coding round, rather it was more of a system design round. I was told to design a simple SMS notification service, where we have to enter the phone number of the person to whom we have to send the SMS. The third round was with the CTO and it was a coding round. A real-life scenario was discussed and we discussed it. It started with the system design, and after the interview time was finished, I was asked to share the code within one day. The task was really interesting and I enjoyed doing it.
