After a short conversation they gave me a coding exercise which was supposed to be submitted within 4 days. The interviewer sounded very excited to give me this opportunity but in the end, after working tirelessly to finish the task (which wasn't easy at all) on time, I submitted it according to their guidelines.
I have been waiting for two weeks for them to give me an answer, so far I haven't heard back from them which was disappointing, I expected at least an answer. They seem to take candidates' time for granted and don't even give an answer to who is rejected. I suggest staying away from them, they do not value time and effort.
