Interview at St. Louis, MO. Started with a HR screening interview, followed by a code challenge. Finished the code challenge and sent back for review. After review, invited for onsite interview. It took around 3 hours. First hour was moreover introducing about their benefits and walk through the offices. I like about the benefit summary however I didn't like the tour to their building because I made my time available for the interview from my work schedule and without making any decision on my candidature they are taking me to the tour which I believe is a waste of time. Second hour was a technical interview asking about the previous projects and experience. Then gave an algorithm coding challenge to validate a string. I answered almost all the questions including the algorithm coding challenge. Third hour was a pair programming and they have a set of unit test cases tied to some functionalities. I was able to progress with the pair programming. I would say almost 90% unit test cases I was able to complete. My pair programmer was also having a good impression. Overall the interview seems easy however after so many followups I got a response from HR saying they are not going to proceed with my candidature for the specified position and would like to proceed for another open position based on my skill. After one more follow up I got a response saying the position is no more active. The usual HR game with Job seekers. At last a message saying 'Wish you good luck in your search' I see few other interview reviews with same experience and same happened to me. Completely waste of time doing the coding challenge, attending onsite interview, a wasteful tour, pair programming. Please make a process for interview which is out of box.
