I submitted my resume for a data scientist position. After few days a recruiter reached out to me telling me that he would like me to interview for another position in data engineering. It was fine by me to do that since the title itself is not the main goal. The first interview was a screening one and it was easy. It was a very traditional interview, however, the only difference I would think of is that the interviewer asked technical questions during the screening. The second interview was a coding interview. It was a two phase process of programming and databases. The programming part was easy, the question is actually easier than all I prepared for and I was ready for a lot of data structure questions, my code ran successfully but the interviewer seemed bitter about it even though it ran and I did not understand that. The database part also was easy, however, the interviewer was very unclear while describing the question so it took me about ten minutes to understand what does he want. He kept changing his requirements and giving me distracting information. I told him I need to know what does he want in order to write the code. I got the code running but to be honest I did not get it running immediately, it took me another ten minutes. After that I felt like he personally did not like me even though my code ran with no mistakes. The most horrible part is that I stayed waiting two weeks and then I emailed him back. He told me he does not know the decision and told me to reach out to the recruiter. The recruiter told me he forgot to send me an email that I was rejected. Honestly, that was very unprofessional. For these three reasons: 1) When doing a coding interview, you have to expect that the person might make a mistake while writing the code. We are human beings. But if he gets it to work then he knows what he is doing 2) When you set a goal for someone and he makes it, please do not tell him he was not good enough. That puts you in a very embarrassing position 3) When you do an interview with someone, even if he is not up to your mighty standards. Please tell him that he is not up to your class
