A recruiter reached out via LinkedIn for the opportunity. After a brief phone call, she sent me an email with study material. A week later, I took the interview.

I was simulating a puzzle game like Candy Crush. I had to write the logic for when three same colors match. I mistakenly studied algorithms because I didn't know it was a frontend engineer role.

If I had studied up on my JavaScript, I would have done better. It was a tough interview overall. Study callbacks.

How would you create the logic of three matching symbols, then disappearing, and three random new colors populating the board?
