#### For interviews, do I need to know everything here?
**No, you don't need to know everything here to prepare for the interview**.
What you are asked in an interview depends on variables such as:
* How much experience you have
* What your technical background is
* What positions you are interviewing for
* Which companies you are interviewing with
* Luck
More experienced candidates are generally expected to know more about system design. Architects or team leads might be expected to know more than individual contributors. Top tech companies are likely to have one or more design interview rounds.
#### Any resources to prep for coding interviews?
