I got the interview by participating in a Kaggle competition hosted by Yelp. There was one code test followed by a phone interview, and then they told me that I was declined.

The position might have been associated with image processing, with which I am not very familiar. They asked questions about machine learning, algorithms, and also image processing, including deep learning.

The code test was an easy problem, and there were many languages available to solve it. I used Python.

For the phone interview, they asked many details about my solution to that Kaggle problem, followed by some machine learning questions. Finally, I was asked to write Python code to randomly shuffle a string.
