I'm confused as to why they'd add in this fine print if they really wanted fresh talent from outside their network: This program is open only to ThoughtSpot's friends and families. For an individual to qualify as ThoughtSpot's friend/family, he/she must be connected to a ThoughtSpot employee on LinkedIn at the time of making a referral. Recruiters and ThoughtSpot employees are not eligible.
