Two interviews and a technical interview

[andrestoga]

Hi,

 

I just want to ask if technical interviews are common in the US? because I will have one and my POI is going to ask me about my knowledge in some courses I took during my undergraduate studies and one day before the interview he will send me a paper for me to study and he will ask me questions about it. He said that I would have 24 hours to study it.

 

Previously, I had an interview with my POI. This will be my second interview with my POI. Not sure also if two interviews are common.

 

Best,
