Meta Senior Software Developer interview questions

They contacted me for the position. HR discussion was good Technical interview was not a great experience. The interviewer had no understanding of the industry I was coming from so there was huge gap. Questions 1. Print the following in html 15 9 2 610 37 48 2. Linked list vs array list 3. hash map 4. project explanation.

I applied through LinkedIn and got a call by HR within a couple of days. Was called for 1st round of onsite interview. It didn't go great but I qualified for the 2nd round which consisted of four interview...two rounds of pure coding, one round of system design, and one round of behavioral plus small coding interview. I didn't do very well in one or more of these and didn't get the offer.
