Most in-house positions require 3-7 years of law firm experience. Entry-level in-house positions are rare, though they exist at large companies with formal training programs.
Generally yes, but it varies. Most in-house attorneys work 45-55 hours/week compared to 60-80+ at law firms. However, busy periods, startups, and senior roles can still be demanding. Research specific companies before assuming "in-house = easy."
Base salaries are often lower, but total compensation including bonuses and equity can be competitive. At tech companies, equity grants can make total comp exceed Big Law. At non-tech companies, comp is typically 10-30% below comparable law firm salaries.
