Never prejudge, never prejudge.
That´s really the worst. The strongest person I´ve met on my team at the moment is somebody I had a chance meeting with at a networking event. We ended up sitting next to each other round a lunch table and it went from there. Never prejudge people, always stay in contact, don´t forget to follow up, the follow up is absolutely essential, people will maybe find themselves in a different position. I learned that people´s situations change every 3-6 months!
