This!
My boss at Weatherford 12 years back is now a Sr. Program Manager at Northrop Grumman. He appreciated everything I did back then and offered me a promotion but I had to leave for Southwest.
Fast forward last year. I applied for a job in Cali making 200K. I hit him up on LinkedIn and he tried to get me plugged in. Unfortunately the position wasn’t in his program but an adjacent program. Use LinkedIn and try to get everybody in your position and above info. You never know when you will need them.
Also, try to plug somebody worth it in a position if possible. It’s hard out here and we all are really just numbers. I know some of you IT boys are “1/1” architects but most of us are 1/10,000.
