Intro call with recruiter, then scheduled a first round coding interview. Coding interview consisted of a single coding question, easy-medium leetcode type of question. I completed the question quite easily and explained optimizations and runtime. Interviewer and I talked for a little while about the company. Standard rejection email from recruiter. I asked for specific feedback. Apparently my score on the coding interview was low on some of the questions. I followed up to get more specifics as to what questions as there was only a single coding question that I got through easily. Recruiter then denied to provide any more specifics. I am unhappy with the lack of clarity, and honestly it feels like the rejection reason is fake. It was a simple coding problem and I got all of the test cases to pass.
