Interview Preparation Tips

Interview preparation tips for other job seekers - Highly unprofessional interview experience with Axtria. Before the process started, I made the HR clear on my expectation and the company agreed. I cleared all my rounds and during the rounds every discussion regarding the expectations were same. Thinking I and the company are on the same page, I saw through the end of the interview. However, during the final salary discussion round the HR got back to stating an offer way way below the expected and agreed upon quote, stating the quote as "Generous". Huge waste of time and effort.
Word of Advice: Communicate clearly. Don't waste a candidate time in such a manner.
Definitely not going to work for a company that doesn't values candidate's time and lies throughout the interview process .
