I am currently an intern in a company in Singapore. My supervisor's colleague gave me a small task and asked me to collate some details about others interns. I did it and sent him an email. He replied "Thanks!". Should I reply back something like "No problem" / "It's alright" or shall I just leave it and don't reply anything? I want to be nice. Is it ok if I just do not reply back anything or is it more polite to at least reply back a "No problem"?
Thanks in advance for any answers.
