You got the interview. You answered all the questions to the best of your ability. You did really well. But what you choose to do next can help you land the job, the mentor or the opportunity.
Send a thank you card.
Seems pretty simple. Because it is.
A personally handwritten thank you card, sent to any person that takes the time to help you and your career, makes a big difference in your relationship. Expressing appreciation is a win-win. The receiver feels good. And this warm and personal gesture (sending a card) helps build your brand as a thoughtful person who expresses sincere gratitude for time or an opportunity provided. In my career, I have become somewhat known for "being good at sending thank you cards." I have even had people tweet photos of my cards. Not a bad thing. Not a bad thing at all.
And if you design a unique card with your monogram on it, you increase the likelihood that your potential boss, mentor or client, will keep your card on their desk and literally look at your name every day.
