The first step was an HR interview where they asked about my salary requirements, which I naively answered.

Next, I had a technical phone interview that included coding on a web whiteboard. After a brief conversation, the interviewer presented the coding question.

I passed this interview and was scheduled for an onsite interview in San Bruno. This involved five hour-long sessions with a lunch break. I felt the first interview went well, but during the second, I neglected to check all the test cases. I was sent home after completing two interviews.

I had to sign an NDA, so I cannot disclose the questions asked onsite. Since I finished early, I had to wait at the airport for eight hours in a terminal with subpar food options.

They booked my flight and hotel, but I have yet to receive reimbursement for my travel expenses.

Take a ladder with 5 steps. Write a function that gives all the possible combinations of either 1, 2, or 3 steps, in any order, to get to the 5th step and returns the total number of combinations.

Some of the possibilities would be [1,1,1,1,1], [1,1,1,2], [1,1,2,1], etc.

Then, he asked the same question but with order not being considered, so [1,1,1,2] and [1,1,2,1] are the same solution.
