The reason people create LinkedIn profiles is to provide more context about themselves to others with whom they have professional interactions.
Checking the interviewer on Linkedin will give you a sense of the person you’ll be meeting with, as well as their career path and tenure with the company. The knowledge can be used to steer the conversation in an advantageous direction.
Do not spout off facts about the interviewer you found from his/her profile or you would come off as creepy.
This is very important o. You must go for interviews prepared on all fronts
I buy into this hack. There is nothing like getting a feel of the person who might be interviewing you but be warned their credential might make them appear intimidating. Or Not. I have experienced both and in each case nailed the job ‘cos I had an idea of the person and I got an insight into some of their interest. You should that too if you have an interview lined up.
