<p>I never received any contact information outside of my interviewer's name and phone number. How should I contact my interviewer, by a text?</p>
<p>IMO a text is a bit informal (although if the interview was really informal then you could text if you feel it’s appropriate); I’d go with a phone call though. If he/she doesn’t answer then just leave a message. It’s a lot more professional and shows more effort than a text message.</p>
