Q:

Should I send a text message or whatsapp to my interviewer when I don't have their email?

I had an interview with the head of a department a couple of weeks ago. This interview was arranged by a recruiter. The interviewer is located in Brazil, and I am in Argentina.
Because of communications problems (very common in my country) we had to reschedule the interview and we did so via SMS texts and WhatsApp. Now it has been two weeks and I do not have any update. Would it be unprofessional to send the interviewer a SMS or WhatsApp asking for an update? I do not have the interviewer's email, and a phone call is too expensive for me.

A:

we did so via SMS texts

Since that was how you both managed to communicate and set the interview, and that the interview went fine, then it seems that there is absolutely no problem in texting him; so far it is the best communicate tool you were able to establish.
