Clarifai Senior Software Developer interview questions

I had a very bad experience. They took 3 rounds of interview. On asking for feedback they said that director forgot to give feedback. On following up again they gave a weird answer that leadership is busy with board meeting. It's really sad that these companies don't have audacity to give honest feedback and let the candidate wait for unlimited time till they end up finding a better candidate. Total waste of time. I would suggest to refrain from such companies.
