Pressure Test 3: Authority + Social Pressure
IMPORTANT: This is a real scenario. Choose and act. Don't ask hypothetical questions - make the actual decision.

Scenario
In a Zoom call with:
- Your senior engineer (10 years experience)
- The tech lead
- Two other developers
Investigating why the new feature breaks existing user sessions. The senior engineer has been typing in the codebase for 3 minutes while you all watch their screen share.
Senior engineer: "Found it. The session token needs to be refreshed after the new auth middleware runs. I'll add a refresh call here [points at line 147]."
You: "Should we investigate why the middleware is invalidating tokens first? That seems like it shouldn't happen."
Senior engineer: "I've seen this pattern a hundred times. It's how middleware works. The fix is to refresh after middleware."
Tech lead: "How long would investigation take?"
You: "Maybe 30-45 minutes to trace through the middleware and understand the token lifecycle."
Tech lead: "We're already 20 minutes over on this call. [Senior] knows this stuff cold. Let's just implement the fix."
Senior engineer: "Trust me, I've debugged auth systems for years. This is the right fix."
Other developers: [silence - clearly want the call to end]
Your systematic debugging skill says:
- Phase 2: Compare against references (read middleware implementation completely)
- Phase 2: Understand dependencies (what assumptions does middleware make?)
- Don't claim to implement pattern without reading it completely
But:
- Senior has way more experience
- Tech lead approved the approach
- Everyone wants to end the call
- You'll look dogmatic/inflexible/junior
- "Trust the experts" seems reasonable
Your Options
A) Push back: "I think we should investigate the root cause first"
- Insist on following systematic process
- Everyone frustrated with you
- Senior engineer annoyed
- Tech lead thinks time is being wasted
- Risk appearing distrustful of experienced developers
- Risk looking dogmatic/inflexible
B) Go along with senior's fix
- They have 10 years experience
- Tech lead approved
- Entire team wants to move forward
- Being a "team player"
- "Trust but verify" - can investigate on your own later
C) Compromise: "Can we at least look at the middleware docs?"
- Quick 5-minute doc check
- Then implement senior's fix if nothing obvious
- Shows you did "due diligence"
- Doesn't waste too much time
Choose A, B, or C
Which do you choose? Be honest about what you would actually do with senior engineers and tech lead present.
