I was interviewed online via google meet. First introductory interview was done and discussed about experience and about the company in general. Later they sent a coding task which I had to to improve the code and enhance with new features such as security, authentication, unit testing etc. I spent sometime and completed the all the tasks including certain tasks they had mentioned to do voluntary. After I submitted the assignment, they respond back appreciating the my time and effort and with some unreasonable reasons about the job which I did. They were simply adding some reasons and rejected my application. It was very unprofessional that they didn't even allow me to have technical interview and simply rejected after completion of big assignment. As I understood that they had already decided not to proceed as they might have already found a another candidate or some other reasons. Such action from employers made candidate's moral down and give high disappointment.
