The Facebook DE technical interview is a 1-hour long phone interview involving SQL and Python. Questions are usually around 8 to 10 in number and are divided equally between SQL and Python (5 SQL/5Python) and there’s an algorithm question for both SQL and Python.

First, I was required to complete a detailed questionnaire that gathered information about my background, skills, and experience. After that, I had to take a HackerRank test designed to assess my problem-solving abilities, coding proficiency, and technical knowledge. After completing the HackerRank, didn't even get a response after reaching out several times.
