hi, i received a call from genting for me to go for interview and the caller told me im going to receive an email about the details, but i still havent receive the email

how long will it takes usually for the email to be sent after they call u for interview? and if i didnt receive the email should i call them to ask about it before my interview?

i received my mail, guess i was too gan jiong earlie

i applied for hr executive, any tips for interview of this job? and in the email it stated that the attire is professional business attire, so does that mean i have to wear a tie as well? or just normal formal attire
