I was first contacted by the recruiter, who asked basic questions about my education and past work experience.

A few days later, a phone interview was scheduled with a senior software engineer.

The interviewer had a strong accent that made it difficult to understand him. I had to ask him to repeat several questions.

The first question was about what happens when you enter a URL into a browser.

Next, we discussed socket communication protocols.

The last three or four questions all related to SQL, and they were usually quite lengthy.

It's advisable to have a notepad handy to write down questions, so you don't have to repeatedly ask for them to be repeated.

Nothing was particularly difficult, but there were a lot of SQL questions for which I was unprepared. Make sure you brush up on your SQL.
