Career Advice About Nutanix

Hello,

I got contacted by a Big tech recruiter recently to interview for Sr. SWE/L5/E5 level. The recruiter said they can skip the phone screen round for me and advance me to virtual onsite interviews directly, probably due to my relevant experience for the team/role.

My question is regarding how to know how much time to buy for interview prep. Since one hurdle (phone screen) is already cleared and this company is one I would like to join, I want to buy enough time to prep well and give my best shot. At the same time, I don't want to give an absurd number of months for this opportunity to go away, and for me to lose momentum which I can use for other companies too.

Sorry I know this is a very non-generic and personal question depending on my skillset to clear this interview. Just sharing some info if it helps you answer -

My current situation - I started preparing for interviews in general a month ago. So I started with brushing up on DS concepts + Algorithms and learning Coding Patterns, and about to start Leetcoding soon. I have not done any preparation for System Design and Behavioral rounds as of now. I have not interviewed since a long time, so my interview skills are quite rusty. I'll probably need to take some mock interviews/practice interviews with other companies as well before this Big tech company's interview.

I feel like the projects I get are more generic and straightforward. I want to start making progress towards senior, but the more complex, larger scope projects are going to the engineers on my team that are more senior. What can I do to start getting those projects?

I've gotten feedback that I could be more of an expert and provide insights more smoothly on past projects I've delivered. However, I've been at the company for many years, so there's a lot of stuff attributed to me. How can I be an expert on all these things without being overwhelmed?
