On Saturday night, I found a company's HR persons LinkedIn request pending on my LinkedIn. I added her and instantly I got an email asking if I were interested in working for X company and they were looking for an immediate response.
I replied back asking what positions are open so I can respond back. I got a reply that they were looking for full stack web developers. I sent my resume to the mentioned email address but I feel very weird talking over at a Saturday night to a HR recruiter.
What is the etiquette of replying back to people on odd timings?
