I had a short phone interview with some preliminary questions. Many questions were scripted and seemed to involve a lot of typing, rather than being specific to my resume or other answers. The technical questions were light.

I was given a development assignment to implement the basics of a word search game. They provided an existing web implementation as an example. The project was supposed to take 10 hours, but I was able to finish it in about half that time.

A few days after submitting, I received a generic form response stating they were not interested. They provided no feedback on what was unsatisfactory about the project. I sent a message back asking if they could provide some constructive criticism so I could understand what I did wrong, but they never responded.

It's unfortunate for an educational company not willing to help me learn a little about myself.

What about Duolingo makes you want to work here?
