Here is a powerful ๐๐ก๐ง๐๐ฅ๐ฉ๐๐๐ช ๐ง๐๐ฃ to help you land a job!
Most people who are skilled enough would be able to clear technical rounds with ease.
But when it comes to ๐ฏ๐ฒ๐ต๐ฎ๐๐ถ๐ผ๐ฟ๐ฎ๐น/๐ฐ๐๐น๐๐๐ฟ๐ฒ ๐ณ๐ถ๐ rounds, some folks may falter and lose the potential offer.
Many companies schedule a behavioral round with a top-level manager in the organization to understand the culture fit (except for freshers).
One needs to clear this round to reach the salary negotiation round.
Here are some tips to clear such rounds:
1๏ธโฃ Once the HR schedules the interview, try to find the LinkedIn profile of the interviewer using the name in their email ID.
2๏ธโฃ Learn more about his/her past experiences and try to strike up a conversation on that during the interview.
3๏ธโฃ This shows that you have done good research and also helps strike a personal connection.
4๏ธโฃ Also, this is the round not just to evaluate if you're a fit for the company, but also to assess if the company is a right fit for you.
5๏ธโฃ Hence, feel free to ask many questions about your role and company to get a clear understanding before taking the offer. This shows that you really care about the role you're getting into.
๐ก ๐๐ผ๐ป๐๐ ๐๐ถ๐ฝ - Be polite yet assertive in such interviews. It impresses a lot of senior folks.
