Interview Officer: "Tell me about Cookies Session and Tokens". Me: "Emm..."

In late 2021, I took an interview with a hotshot IT company for a front end engineer position. During the interview process, the interview officer’s question of “Tell me about cookie session and token” got me into my knowledge blind spot.

I will be explaining some details around “cookies” “sessions” and “tokens”. Meanwhile, hope this article will remind everyone to strengthen related knowledge points so that it could come to help any day in the future when necessary.

It was an online interview with only interview officer and me in that meeting. The officer was a bit late but he was still very nice and polite. He introduced himself and the interview flow.

There’re quite few casual talks among the interview and the whole process took about 50 min (should be 1 hour but he was late, so 10 min was gone…). I did my best to answer each questions as I could.

Interview officer: “How much do you know about ‘Sessions’ ‘Cookies’ and ‘Tokens’? Could you explain by giving some examples?”
