It's always good to send a thank you email immediately after the interview, even an informational interview. Glassdoor recommends sending an email within 24 to 48 hours. If you haven't heard from the company in 7 to 10 days, it's probably safe to send a follow-up email. If your interviewer has outlined the next steps and said, for example, that you'll hear from them in two or three weeks, follow up.
Otherwise, if they don't specify a deadline, plan to send a thank you email within 12 hours of the interview and follow up within a week. In fact, send a short thank you email immediately after any formal, informal, telephone, or video interview you have. Job searching is a delicate mix of conversation and listening, excitement and anxiety, perseverance and luck. The sooner the better on the same day of the interview or the next day, but definitely not later than 24 hours after the interview.
You should ask about the result of the interview in a polite and professional manner so that they don't see you as a pest. In addition, Heath suggests resources such as The Muse and Career Contessa that can help you in your job search through scripts, templates and infographics on Instagram. You can also share something interesting that you've done since the interview that contributes to your application, such as taking a course or improving a skill. And here's another example of a follow-up email after a job interview if you've been offered another position.
When you're looking for work, Heath recommends creating a schedule where you send five to 15 applications every day for five days a week. You prepare a cover letter and a resume, send them and wait to hear about a possible interview. Not all recruiters will take the time to give you that opinion, but it's often possible that you'll receive specific advice that can improve your chances of moving on to the next round and, who knows, could lead to a different job offer in the future. Interacting with an employer by carefully commenting on their LinkedIn posts, attending a virtual job fair you're at, or visiting their physical store can leave the best mark.
Being too anxious or pushy (at best) will seem annoying and (at worst) could affect your chances of getting the job.
