Update:I am shortlisted for second round interview. HR says I am one of the final two candidates.Fingers crossed! Thank you for the replies.
I sent a thank you note to the hiring manager after an interview. They replied saying they thought I was great, they have 2 more candidates to go through and will move on to second interviews soon. They sent me a LinkedIn connection request after the email and viewed my profile. I was the first candidate they interviewed.
I understand it could just be a company process. Just wanted to know if anyone had similar interview experience before? Do recruiters check every candidate's LinkedIn during the hiring process?
