Reply to First serious dj job

Hi all! i need some help as im going trying to get a job at a local club here. the bar manager has a position for thursday, friday, and saturday evening s. ive played a crap ton of house partys and a few club events where they switch djs out every hour and a half and i feel like im technically up to it but im kind of nervous about playing for 5 hours 3 evening s a week. My main concern is that i play alot of "edm" and top 40. I dont really know what to expect in a club setting where i play 3 evening s a week. anyone have any pointers or advice for me?
