It isnt always deliberate. I know companies that were two male founders of a specific race that then hired people they knew from their networks for their first few hires. All of a sudden they realized they were a 10+ person company and everyone was exactly like them. All of a sudden, hiring anyone who wasnt very like them became difficult. Have you ever tried to hire a female for an all male company? Have you ever tried to hire a Muslim for a company that is entirely Orthodox Jewish? Sometimes you just hire who you know until you realize you've created an environment that might be very difficult to grow further.
