The selection process started with a coding round. Had 1 hour and had to solve 2 questions. The question was a medium type question (both sliding window questions)... The first question was something like "Maximum length of the substring to be removed so of the permutations of the remaining form a palindrome". I don't remember the 2nd question. The selected peeps had the second round on the same day. It was a 4 hour hackthon round. It was really good and fun. After that, the selected students were invited for tech round and HR round on another day. The tech round was about 90mins long and had system design questions.

They made us wait for 6 hours!!! Worst interview experience ever. The first round was an online aptitude test. Then, for further rounds, we had to visit the office three times: 1. Programming round 2. Technical round (2 rounds) 3. Supposed to be an HR round, but they conducted another technical interview instead. Even after conducting 5 rounds, they still couldn't make a decision. Some candidates had online interviews even after coming to the office. They made us wait for 6 hours on our second visit to the office for the technical round. After keeping us waiting for six hours, they said, "No pain, no gain." Most of candidates were frustrated, but no one expressed it fearing its effect on candidacy. On the day that was supposed to be the HR round, they conducted a technical round instead. After completing the technical round before noon, most of us were told to wait, only to be informed later (around 7 PM) that they couldn't conduct the HR round that day. I feel bad for the employees working there. They are probably being treated similarly. Thank you, KeyValue Software Systems, for wasting our time.
