I had a phone interview first. During the phone interview I was asked some basic HTML/CSS/JS questions. Then I had a phone call and was invited to onsite interview. Onsite interview was really positive experience. It was more conversational than technical.

Interview was pretty simple and straightforward, and was catered more to culture fit. There were some basic HTML, CSS, and JS questions, but none that were too difficult. If you use the CSS pre-processor Sass, it will definitely help you in your interview. The team was super friendly and did not throw any curve balls. Basically, there was no white-boarding, just talking about certain concepts followed up with some culture fit questions.
