Sigmen Technologies Solutions interview questions

I've applied online for this position, they've called and arrange the interview. First round is virtual and then you have to visit their office for a F2F interview if selected. In the prefixed virtual interview I have to wait a lot for the interviewer to come that's a negetive impression. I don't like their attitude and I don't think I can work with them so I have rejected the opportunity. I've talked to their ex employees as well and none of them suggested to join them. This is the one of the rare company where their HR gave them 1 star review and doesn't recommend them.
