X Software Developer interview questions

The take home question was to write a yaml parser. Design gmail was the architecture question. We talked a lot about scaling and reliability. Walk through resume line by line. Talk with manager about why Twitter.

I got an internal referral by my friend. The recruiter contacted me through in 2 days, ask me to go through an online pre-screen where I have to solve two easy coding tests like binary tree traverse. 2 days after I passed that an phone interview was scheduled. The phone interview interviewer was nice and respectful. Two knowledge based question was aksed, then I was asked to solve a problem in an online code editor.
