FAQ
Is this only for engineers at big tech companies?
No — the patterns apply to interviews at startups, mid-stage companies, and FAANG alike. System design scope and comp ranges vary, but the frameworks don't.
I'm a senior engineer targeting my first lead role. Is this right for me?
That's exactly who this is written for. The guide covers where the bar changes between senior and lead, and specifically how to reframe your existing experience to communicate at that level.
What if I'm already staff-level and targeting principal?
Sections 3 and 4 will be most relevant. The cross-team influence and comp negotiation content applies directly to principal-level conversations.
