With more than nine years of experience in Product Design, I separate my career into 3 phases:

  • The first two years ⎼ Gain experience: Say “Yes” to everything and grind experience.

But they rejected my offer!

At that time, I thought that my offer was a suitable solution to build a cooperative relationship. So I felt a bit down when that startup team rejected, but I never asked them why they made such a decision. …
