Technical Behavioral
The interviewer had a pathetic tone and acted like candidates were beggars. He was loud and rude, which could easily freak out candidates who put in a lot of time and effort preparing and have hopes from the company. It's sad to see such unprofessional behavior. It's useless to have so much technical experience if you don't know how to talk politely. I agree I lacked expertise in many questions, but the interviewers certainly lacked basic manners. PLEASE TRAIN YOUR 'SOME EMPLOYEES' ON HOW TO BE GENTLE WITH THEIR TONE WHILE INTERVIEWING.... CANDIDATES DO HAVE SELF RESPECT. I hope you are hearing this, Jio!
