While i appreciate the interview process.I was surprised with the technical skills of two gentleman who took interview. NOT EVEN A SINGLE QUESTION REGARDING MY CORE DOMAIN SKILLS.Because they them-self don't know or they don't know how to take a technical interview. YOU NEED TO LEARN A LOT FROM OTHER COMPANIES,EVEN A START-UP COMPANY CAN TEACH YOU HOW TO TAKE A TECHNICAL INTERVIEW. I'm not an HR,but i have taken so many Technical Interviews so far and i always share the feedback with the candidates because we never know how good they can be next time when they attend an interview.So it is our responsibility to appreciate their time and efforts and guide them properly to be successful going forward. After promising to me that results will be shared after two weeks,till now it is not done .
