I applied through a college or university. The process took 4 weeks.

There were two interviews. The first was a technical pair-programming round lasting 45 to 60 minutes. The second was a behavioral round with a manager, who was likely to be your soon-to-be team lead. For the technical portion, I believe they expect you to pass all test cases, but I can't confirm. I recommend clarifying any ambiguities and having a rough plan, maybe even writing it out in comments so that the interviewer understands your thought process. Overall, it was fairly straightforward.

The final manager round was likely with a manager that you would be working with if you got the job. Make sure you bring a side project and know the ins and outs of it well enough. This can include things such as design choices, testing, improvements, and requirements, as they want to understand your decisions and thought process. An offer letter arrived within about 1 week.

Design a stock matching system such that the system matches the highest buying price for a given quantity with the highest selling price for a given quantity. You can assume that the data for each stock ID is given as part of a list/array data structure for your function and is processed sequentially. The list contains transaction data of a stock class type, which is composed of stock name, cost, quantity, and Buy/Sell. Your job is to implement a system that is able to manage and pair these stocks given the above rules. Feel free to use an object-oriented approach.
