Meta Software Engineer interview experience

In my case, the later interview mainly centered around medium leetcode, and I was also expecting an additional round related to operating systems concepts, but I didn’t continue past this stage.

In the screen itself, I had about an hour and it was split across specific topics: string parsing for the first part, then a security scenario, and there was also a behavioral component. The interviewer was helpful and made it feel manageable, and the security discussion leaned into threat modeling. Even though the overall pace was intense, I didn’t feel completely lost—I just couldn’t carry it far
