Get feedback and send a ‘thank you’ letter
After the interview is over, it's better not to be left hanging. Closure is necessary. Ask the interviewer when they'll let you know their decision. Also find out if it's okay for you to send them a follow up. If there is no response after a week or two, send a follow up with a ‘thank you' letter. The ‘thank you' letter is essential to reiterate your interest in and suitability for the job, and to stay top-of-mind with the employer in a favourable way.
