As a job seeker, you’d want to send a thank you letter after having interviewed by the interviewer.
This is not only good for personal interviews but also for phone interviews – i.e. after the phone interview.
These days, phone interviews serve as the first interviewing round by many employers. Phone interviews have the same importance as the face-to-face interviews because it is the first hiring selection process.

Don’t miss this job opportunity just because you were interviewed over the phone – The thank you letter not only reminds the employer about you as an applicant but also reiterates your interest in the job.
Therefore, you may send thank-you email after phone interview within 24 hours after that telephone interview.
Even better – If you want to add a personal touch to your ‘thanks’, you can hand write a letter and send it by mail.
