FULL DISCUSSION
 

This is all well and good...brings back a lot of memories from undergrad school.

But after enduring such an interview from a company, PLEASE PLEASE PLEASE don't forget to then ask your interviewer how they've used/applied said "algorithms, data structures, design, optimization and honestly just an ever growing basket of subjects" in their CURRENT work.

If you get a blank stare back, you'll know that you were just put through an "interview" that was essentially algorithm hazing and nothing more. I'd seriously question whether or not I'd want to work for this company.

 

100% this! Same with not allowing you to use Google as you attempt to formulate a solution. I assume you would be allowed to use Google day-to-day as you perform your job, right?

 
 

Exactly! I'm disappointed by how many people accept these whiteboarding rituals as a necessary or unavoidable evil. They aren't. There are plenty of companies out there that offer more sane alternatives that mirror day-to-day work.

 

This x 1000. I interviewed with a Big Name Company once, early in my career, and was asked some question about implementing a AVL tree or some such. I asked the guy ( and it was a guy because they all were at Big Name Company, but that's a diff issue ) if he had ever, in his entire working life at that place, ever implemented an AVL tree, or any other primitive data structure from scratch. When he said "no", I asked why they were asking me how to do it. He said because they always asked that question. I said I'd answer when I had my data structures book handy. I got the gig anyway.

These questions are pointless. I'm a hiring manager now. I never ask interviewees questions about how to implement basic structures or algorithms. If someone is rolling their own now, they need to have a damn good reason for it. However, I will ask questions to tease out if they understand WHEN AND HOW TO USE different algorithms, structures, design patterns, etc, and the tradeoffs associates with those choices. I think that is fair game, and also a better indicator of what kind of software engineer you will be.

If you can code up a quick sort, but I don't ask you that kind of sort to use in a given situation , and then don't find out until after I hire you that you use bubble sorts for everything, me knowing you can code a quick sort is not terribly helpful.
