O.C. Tanner Senior Java Developer interview questions

i was interviewed at hyderabad very unprofessional first they never respect candidate time they will start interview after 45 mins wait i went there twice it happened both the times first round they will search questions infront of you in internet and expect to you answer same. coming to second round very arrogant guy came and asked some programs and started java if u ask him to repeat question he show true colors and talk unprofessionally its my mistake to go to this company very unprofessional attitude no one wait unnecessarily on week days give some training to ppl who take interviews so that they know basic etiquettes. coming to company reviews after applying filter for hyderabad u can see 4 reviews on same day i doubt the reviews also. there ofc looks good but have to pay for parking
