The HR Screening was pretty standard. Was asked basic things such as why I want to join the company, what is my history with software technologies and etc. Just be enthusiastic and honest about wanting to join the company, you'll be able to make through this stage. The next step was to come onsite for a standard Data Structures and Algorithms session, followed by a backend/front-end pairing session (you can choose between the two). The data structure/algorithm questions were fairly straightforward and I would say at worst leet-code medium. I finished it with ease and they seemed impressed. The engineers were really helpful for this segment and very encouraging. The pairing session was a different story. I managed to complete the task but with little to no help. Every time I engaged them to ask for feedback while I was doing it, they just nodded and said yeah sure. I have no idea what they wanted but in my opinion I feel like I was able to complete the task. A day later I was emailed saying I wasn't a good fit and they were moving forward with other candidates. All in all, I would say the HR process was very smooth and quick, data structures and algorithms portion was also handled well. Perhaps they should move towards a more industry standard of conducting System design questions rather than get people to code up an API in less than an hour.
