I recently attended a hiring event for a bookstore position that involved stocking and customer service. The interview went well, and I received a business card from the interviewer along with their email address. I've been pondering whether I should send a thank you email after the interview. I read various opinions online, and while some say it’s a good idea to express gratitude and reiterate my interest in the position, I'm unsure if it's necessary in this case. I want to make a good impression, but I’m also considering whether it might be more effective to ask additional questions about the job instead. I’d love to hear thoughts on whether sending a thank you email is beneficial or just a formality.
