Is an interview follow up letter better than a follow up call?

Both are important. You shouldn't consider sending a job interview follow up letter in lieu of a follow up cal. Both are key to demonstrating your continued enthusiasm for the company and for the job. However, there are some differences. The interview follow up letter is primarily a part of business etiquette. You should thank the interviewer for their time. The call, on the other hand, is a chance to check on the status of the position and see if you're still being considered for the job. You should send the letter immediately and can wait five to ten days before making a call.
