Just talk to the person, ask them about projects they’ve worked on, problems they’ve solved etc. you’ll learn far more about them that way than getting them to put on a dog and pony show at a whiteboard!
P. S. I hate coding interviews.
But, yes, this is more work on the recruiting side.
As a side note, I totally get it why large organizations would use Leetcode though. It does help filter out false positives if you're willing and able to bear the cost of passing on many good candidates.
"What is a binary tree" will filter out most of the bullshitters.
None of this stuff is rocket science. We have a responsibility not to be lazy when interviewing people.
Not really silver-tongued candidates? Well, what's the problem? Unless you are looking explicitly for silver-tongued candidates, you should ignore this "trait".
I don't want to know if you can do specific things, if you can't you'll learn, but I do want to know if I'm gonna find it easy to get along with you, if you seem like an interesting person, and if I can stand being in a small room with you for 7 hours a day.
I suspect this is just another kind of bias, but I've had good results.
I think an extra hour to talk will give me more information than watching them balance a binary tree.
For many people the stress of the leetcode session is just awful, I don’t think it’s a nice thing to inflict on someone if you’re ultimately going to disregard the outcome anyway!
