After telling they were interested on me, the HR guy didn't show up to the interviews TWICE. After finally showing up (late, ofc), the interviewer had only 10 mins for me, where he asked me to do a coding challenge without supervision. After doing it and submitting it, I didn't get any feedback for two weeks, so I asked. The HR guy ignored me, so I told him again the next week. Surprise, he kept ignoring my emails. 4 weeks after, I send a last email and he answered with a very brief: Sorry we got someone else.
