> You: I'm ready

> Interviewer: Great! Here's your question: Can you explain the difference between a stack and a queue data structure?

> You: Definitely.

> Interviewer: Okay, great! A stack and a queue are both abstract data types that can be used to store and manipulate collections of data. However, they differ in their approach to managing their elements. A stack is a Last-In-First-Out (LIFO) data structure that allows elements to be added and removed from the top of the stack. The topmost element in the stack is also known as the "head" of the stack. When an element is added to the stack, it becomes the new head. When an element is removed from the stack, the head is removed first. On the other hand, a queue is a First-In-First-Out (FIFO) data structure that allows elements to be added to the back of the queue and removed from the front of the queue. The front of the queue is also known as the "head" of the queue, while the back of the queue is known as the "tail". When an element is added to the queue, it becomes the new tail. When an element is removed from the queue, the head is removed first. In summary, the main difference between a stack and a queue is the order in which elements are added and removed. A stack follows the LIFO order, while a queue follows the FIFO order.

> You: Cool

And then it just keeps prattling on about it, without ever actually testing my knowledge.

And even if I start off saying "No, not really", it spits out the answer just the same.

How does this help me prepare? (:

In real life, the interviewer probes the depths of your knowledge.

I do like the UI, though. Nice job there, it's easy and intuitive.

Edit: @marcelc63: No need to apologize. I had fun trying it out and wish you all the best. Don't give up! Feel free to ping me when you're ready, metadat.luvs.u@big-gmail

Hi! Thanks for trying it out.

Yes I do admit the interview is not perfect yet. More prompt engineering to optimize. I think with a few more optimization we can get ChatGPT to conduct a more quality interview session.

Sorry you didn't find value in the mvp yet, my teammate and I was taking ChatGPT API for a spin and share it as it. In hindsight we could've done more optimization before posting here.

If it's ok, I'll let you know after we optimize the prompt for you to try it again.

Thanks for the feedback, we appreciate it a lot

To be fair, “definitely” would not be a good answer to that question in a real interview :)
It's a direct answer to a fairly broad and vague qualifying question, intended to be a response to kick off a dialog and proceed to discuss what the real question is.

Interviews aren't and shouldn't be about regurgitating rote memorization.
