I had recently had a phone interview with the head of a company. Some hours later, I noticed this person had checked my LinkedIn profile several hours ago, prior to the interview.
With only an intention to thank the person for an interview, I sent a small thank you note as part of a LinkedIn connection request. However, I soon realized that doing something like this may have been inappropriate, as stated on this page:
That line definitely gets crossed when a candidate sends a request to their interviewer before or immediately after an interview to connect on LinkedIn. If you get the job by all means connect, but until then it can make you seem presumptuous as you are implying a level of familiarity that doesn’t exist.
What would be the best course of action to minimize misunderstanding? This person doesn't have a publicly-available email address.
