Eggs are versatile and require special handling, so egg dishes are good for showing both creativity and technique. There's a lot to pay attention to: cracking eggs, picking cooking vessels and utensils, seasoning, plating, texture, how fast you move, etc.

Efficiently making an egg dish that can be served to customers would be a pass. The standards depend on the restaurant and the chef that does the interview.

Eggs are also extremely easy to overcook (I'm far from a professional, I think around ~70C/160F, and the temperature tolerance band is quite small), so there's a lot of techniques in controlling the temperature.
