I have been working at Platinum Equity full-time (More than 8 years)
Learn a ton. Great experience.
None from my perspective. You get what you put in.
I applied through a recruiter. The process took 3+ months. I interviewed at Platinum Equity (Beverly Hills, CA) in July 2015.
Phone interviews with two (2) department lawyers; in-person interviews with four department employees--general counsel, two (2) department lawyers, and a senior paralegal. The questions were primarily superficial, with a relative few on more substantive topics.
