I had applied for a job position, for which the interviewer replied me back after a couple of days. However, he started his email with 'Sorry for the late reply'. Now to revert him back with a response, I want to know what can I say back to the his 'Sorry for the late reply' statement. Shall I just write "No problem. (continue with main body of response)" or "It's ok. (continue with main body of response)" ?
PS: The question was originally asked at https://english.stackexchange.com/q/110616/41946. But based on the comment received there, I am asking the question here.
