I had an interview with this company on December 19, 2018 and I think it went well. After the interview the interviewer told me that he will send me an email that we will be in touch so if I had any questions, I could ask him during holidays. I didn't receive anything from him, so I sent an email to the HR on January 2, 2019, thanking her and asking if she could forward my email to the interviewer so I could follow up with him. Then she replied back with this email :
"I have forwarded your email to Alex and we are currently looking into the employment status."
Since then I haven't heard back from the company (neither the interviewer or the HR). So I was wondering when is a good time to follow up with them.
P.S. Update: I contacted them and they told me they decided not to go forward with my application. It's definitely better than waiting.
