1 phone screen, asking about my project, and 1 coding session.

I was expecting a very tough scenario or edge case where I'd need to use advanced data structures like a stack, LinkedList, or a complex algorithm. However, the requirement was only to search by ID.

Me: Is there a limit to the size of the pallet? Interviewer: No

Me: Is there a concurrent scenario? Interviewer: No

Me: Does it require first-in, first-out or last-in, first-out? Interviewer: No

Me: If there are different types of pallet collections that need different implementations, I might need to use an interface or generic types. Interviewer: No

Me: Only search by ID? Interviewer: Yes

Okay, I implemented it with a simple, pure HashMap. The interviewer seemed only interested in whether I checked for null at each step. I have no clue what this interview was looking for. If you want to test if a coder has clean code, algorithm, and data structure knowledge, go ahead with LeetCode medium to hard questions. If you want to check if a candidate has the ability to solve a complex question, please provide more difficult requirements.

After finishing all methods, I was asked how to find the total weight of all pallets loaded by time period.

Okay, please, if you need me to solve this question using algorithms or Java/Golang code, tell me at the beginning, and let's use a different data structure. Otherwise, let's use something called a database query.

After receiving the reject email, I asked if the recruiter could forward feedback, but there was no response.

My previous project, but I never dug into the details, which I expected for tons of very technical discussion.

Add a pallet into a trailer with load() and upload functions.
