What should you do after completing a job interview?

After completing a job interview, sending a follow-up email thanking the interviewer is a professional and courteous practice. This gesture demonstrates appreciation for the interviewer's time and reinforces your interest in the position. It allows you to reiterate your key qualifications and express enthusiasm for the opportunity, which can help keep you fresh in the interviewer's mind as they make their hiring decision. This step can also contribute positively to the overall impression you left during the interview and may set you apart from other candidates who do not take this initiative.

In contrast, the other options lack the professionalism and strategic advantage that a follow-up email provides. Forgetting about the interview and moving on can result in missed opportunities for networking and future communication. Posting on social media might not present the interview in a professional light and could even reflect poorly on you if not done thoughtfully. Waiting for the company to contact you without any follow-up may prolong the process, and allow other candidates to stand out, while you could take proactive steps to strengthen your candidacy.
