Very unprofessional. Very rude interviewers. I received an offer on the phone after an interview and coding test and I was told I would receive it in a day or two. They stalled me for three weeks and I was told eventually that they can only offer me 15K less than what I was supposed to get. I'm pretty sure that is their technique to con you into accepting a bad job offer.
I was emailed 4 month later if I am still interested to do an interview. I said yes, but again to email to schedule the interview. Then I received an email in the morning (10:00 AM) that can you come to an interview on the same day? Hell no. I'm at work. Eventually I went there in the after noon around 6 and office was full of people working hard. I'm pretty sure life-work balance does not exist. I did not hear from them after my 4th interview. So unprofessional.
Also their recruiter A.P PhD is a con man like them.
