Rocksport interview questions

Thr company is highly unprofessional, they raised the offer and withdrawal(after 4-5 days) saying it raised the offer by mistake. Had visited office twice, it's filthy and gives negative vibes. In name of interview, they were just casually discussing..Even people were conducting interviews their knowledge and experience is doubtful. People who are going to there be cautious.. they have recently raised some funds..else everything is pathetic.. Be mindful if you are resigning from your current job basis on their offer letter.
