Based on two testing environment you might get a call for an interview which i did receive. I was interrogated(yes, It wasn't a professional discussion as i expected to have) for 1hr35mins by two gentlemen. One of them was fine and was able to communicate properly and other asked questions from Daniel Miessler Blog(I found out after two days). I quite enjoyed the other guy who asked reasonable question based on onion model interviewing and i was able to answer each of them.

The interview was fully technical. The interviewer will be one of the Security Analyst from their team. The analyst should have basic/advanced knowledge of OWASP 10, basic android pentesting, network pentesting, etc. The required training will be given to analysts based on their knowledge.
