I've been a software engineer for 24 years. I've never ever needed to write a binary search function.
@TheAbhorrent1
This is ridiculous I've been a binary search tree for 30 years and never once have I had a software engineer traverse me.

Interview: Search a binary tree. Job: Please make CTA blue, client said her favorite color is blue.
@patrioticgrind
This interviewer giving a lot of guidance. I’d be grateful to have him. Other interviews don’t really do that
@jedilec
1. Read the question twice. Look at the examples. 2. Clarify the details of the definitions. In this case what is a "successor" 3. Clarify the constraints. 4. Determine edge cases 5. Choose an algorithm associated with the question. e.g. trees -> inorder, pre-order, post-order, bfs, dfs. 6. Implement the naive solution and discuss time and space. Write clean code. 7. If time talk about how you will improve the solution and implement if you can.
@Gotejjeken
As a software engineer, I swear the only time questions like these matter are in college. Maybe interview for top 5 percent of jobs, but the other 95 percent definitely not going this in depth. Companies need bodies not rainman.

I've been a software engineer for 25 years. I have interviewed TONS of prospects. I've NEVER had them code without using a compiler. Typically, I would just come up with a project, give them the directions and let them sit in front of a computer for one hour and hammer it out the way they normally would. They get the compiler, internet, whatever they need. Now, given that, I do expect o see much better code than what would be written in notepad :) As long as they can then thoroughly explain their project to me I'm good with it.
@Mrdresden
10 years in the industry and I echo what others have said here. There is no particular reason to know how to solve this problem from memory. However being able to work through it is the real test here. If I were ever to sit over someone for a coding interview like this, I wouldn't really be looking for the correct solution, rather the approach and how long the individual stick with it.
@ikeo8666
this is one of those interviews where you can get the interviewer to give you the answers because it makes them feel smart. so easy
@JimzZel
My biggest advice for interviews like this "communication is key".. speak with the guy who is interviewing you say what you think. It gives the guy an idea on how you think. Most of the time it is not about the technical knowledge itself but how you handle it.
@danh3363
95% of devs will never need this. The real question is how well can the devs take requirements and create an effective solution.
@JM-gz1ej
Majority of software engineers never work on these nonsense in day to day work
@Asiagosik
During Bloomberg technical rounds, the person being interviewed isn't usually asked to compile the code
@nomadsome
Engineers in this video: let's do some real algorithm work to get hired Founders of 95% products: I need to integrate Stripe with WordPress
@akzarma
*Code runs successfully* Him: cool Interviewer: cool. *leaves the meeting*
@michaelnaylor8245
It seems like they’re interviewing each other. I think it was more of a collaborative problem solving exercise
@vladandrei51
These kinds of cliche questions are never ever used in real-life situations. You can literally learn by heart those types of things and pass any interview with breeze but have no idea what you're doing otherwise.
@jacquesduplessis8944
So I need a cheaufeur to drive me around: skills required are, mechanical engineering to build the limo each time I need a lift to the office.
@itsukiuehara6292
maybe he is hiring for a "binary tree interviewer position" that is why they are discussing binary trees.
