Many interviews are not pure whiteboard algos. And many interview processes are different, each company is unique.

When I interviewed a couple of years ago, I saw various kinds of interviews at companies:

* 1-2hr on site coding exercise, with the internet, alone.

* 'Here is a 100loc piece of code, fix all the problems with it'.

* Chat with product / manager / team lunch. ('Are you an asshole' test / 'culture' interview / scenario testing)

* Design / outline an app that does X, with boxes and lines on a whiteboard.

* Solve this algorithmic problem on a white board / on your computer.

The reason why everyone freaks out about the algo interview it's the only interview type that most engineers have to prepare for. The other 4 usually you don't have to do much prep work at all.
