I worked at Wynn Resorts part-time
Union, Employee Dining Room, provided uniforms
Seasonal, no requested days off
The process took 1+ week. I interviewed at Wynn Resorts (Las Vegas, NV) in May 2017.
First had a meet & greet type interview so they can rule out the people who had no chance. Got invited back to a group panel interview that was held the next day. Had a minute to talk about why I should get the job in front of everyone the executives and all other candidates.
