Behavior Interview Session (Mock & Coach): Common Red Flags - Part I

Red Flags

In this mock session, the answer of the candidate has revealed several red flags, which lead to a lack of signals to obtain his Staff Engineer Offer.

In the first set of questions regarding introduction and team vision, here are the notable red flags.

Red Flag 1.1 - Blurred Leadership Identity

The candidate don’t make it clear what you own vs. you support. Like saying “I contribute in many ways” and “I don’t define the roadmap” makes him sound like a strong Senior Engineer — not a Staff-level engineer. This is a common redflag that lacks enough scope in his target level during the interview

Red Flag 1.2 - Mis-alignment

For both examples—dashboards and scripts—are tools, not strategic levers. Nothing wrong with them, but Meta expects alignment through systemic or architectural shifts, not just operational polish.

Red Flag 1.3 - Accountability Scope

“I usually defer to our tech lead” signals a lack of proactive leadership. Staff Engineers shape direction—they don’t just weigh in and step back. You also need to show your accountability and ownership when coming to decisions.

In the second set of questions regarding project deep dive, here are the notable red flags.

Red Flag 2.1 - Passive Ownership

The wording the candidate used like “I wouldn’t say I was the first to raise it...” and “I was one of the early voices” signals a lack of initiative. A Staff Engineer should own the why as well as the how.

Red Flag 2.2 - Lack of Strategic Communication

Tracking via Slack/Confluence is fine for team-level updates, but there’s no mention of influence, exec buy-in, or shaping org priorities.

Red Flag 2.3 - Over-indexing on Execution

The candidate was doing a lot, but he failed to frame the story. This is one of the most common Staff+ traps: being a technical anchor without a narrative arc.

In the third set of questions regarding influence and alignment, here are the notable red flags.

Red Flag 3.1 - Soft Influence, No Escalation

“I didn’t escalate formally—I just kept showing up” implies influence by persistence, not by strategic leverage. Staff Engineers need to navigate organizational friction intentionally.

Red Flag 3.2 - No Roadmap Inclusion

This project wasn’t tied to any roadmap, and the candidate didn’t push to make it one. That shows low prioritization influence.

Red Flag 3.3 - Missed Leadership Moments

The follow-up answer reveals self-awareness (“should’ve aligned earlier”), but there’s no growth arc, meaning no evidence they’re applying that learning now.
