Valuation at boutiques?

Hey IB monkeys. I was wondering how daily activities at boutiques differ from the routine at bigger banks. By "boutique" I don't mean Lazard or Rothschild, but small boutiques (up to 20 people I'd say). So, small investment banks/advisory firms targeting mostly not listed companies.

I asked this question during an interview and I was told that analysts do TONS of pitching, and valuation is mostly done through multiples and comparable companies. No DCF, basically, which was quite surprising.

Based on your experience and on what you heard, how is the routine of a boutique analyst different from the one of a BB/large boutique analyst?

Thanks!
