Interview preparation tips for other job seekers - I had a very negative or wrost experiance with ThoughtWorks during the interview I was able to solve all code pairing programming question without any mistakes or not taking a single hints. It seemed like everything was going well. However after two days i received a rejection mail.

HR said that during the interview my thought process didn't align with the interviewer. Honestly, during the 2 hours of interview. They never mentioned any concerns about my approach or wanting more from me. They simply presented a problems and i solved then they moved on to the next one.

If they weren't happy with my approach, they should have told me to explain further or said that wanted a more optimal soltion something like.

As a fresher, handling such pressure is challenging, especially since we face more struggles than experienced candidates. If a company is not inclined to hire freshers, they should avoid accepting our applications and avoid playing with our emotions.
