Here is a powerful 𝗜𝗡𝗧𝗘𝗥𝗩𝗜𝗘𝗪 𝗧𝗜𝗣 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 𝗯𝗲𝗵𝗮𝘃𝗶𝗼𝗿𝗮𝗹/𝗰𝘂𝗹𝘁𝘂𝗿𝗲 𝗳𝗶𝘁 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: 1️⃣ Once the HR schedules the interview, try to find the LinkedIn profile of the interviewer using the name in their email ID. 2️⃣ Learn more about his/her past experiences and try to strike up a conversation on that during the interview. 3️⃣ This shows that you have done good research and also helps strike a personal connection. 4️⃣ 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. 5️⃣ 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. 💡 𝗕𝗼𝗻𝘂𝘀 𝘁𝗶𝗽 - Be polite yet assertive in such interviews. It impresses a lot of senior folks.
