Cloudium Software Full Stack Developer interview questions

I was interviewed by cloudium software for the full stack developer position. The interview consisted of 4 rounds , I have completed 3 technical rounds and was told to wait for the final phone call round, Even before the final phone call round I was informed that cloudium software is not moving forward with the application, since the company feels like my qualifications weren’t aligning with the job requirement . The process Took around 1 month.
