Interviewing at lower MM PE shops in London

Hi guys,

I have c. 4-5 years of experience in M&A (o/w 3 in continental Europe and 1 in UK) and am now interviewing at lower MM PE shops in London (early stage, haven't had any interviews yet). 

I have 2 questions for you:

1) Anybody knows how the interviews might look like in terms of technical questions/case studies?

2) What level of compensation and grade should I aim to get? Are they basing compensation on what I have now or do they have internal standards? 

Thanks for your help
