Coding deep dive and design questions asked

90% LC for coding but design is occasionally a one-off relational question (like, please design a hotel booking system, please design a platform for customers to purchase tickets) and for the LC is questions they definitely want you to run through edge cases, factor in time/space complexities if applicable, and the biggest one is gather requirements up front. For design, high level and simple but you should plan to modify or add to it to make it more complex with proving questions they ask. You can actually be a fairly OK/average coder during the live interviews but if you communicate well you’ll do great. For any behavioral questions make sure to always explain what YOU owned instead of what your team owned. That always gets people.

That sounds about right. Out of curiosity, what country are you in? I’m very surprised you were sent a HR assessment for a senior-level role. Typically we use them for SDE 2 & below in the US but it also could be the specific team.
