The complete hiring framework: What I learned scaling to 130 employees.
After conducting 500+ interviews, making 130+ hires (and several bad ones), I learned these lessons the expensive way. Here's everything I wish I'd known.
Dear readers,
I’m excited to share my fifth framework with you. This one focuses on how to hire the right people and avoid the mistakes that quietly kill companies.
I walk you through the exact principles I used while scaling to 130+ employees, the small hiring decisions that made an outsized difference, and why hiring is one of the highest-leverage responsibilities a founder has.
Best,
Xaver

Why This Matters
Hiring is the highest-leverage activity a founder does.
Get it right: Your company compounds.
Get it wrong: Everything stalls.
At e-bot7, we went from 0 to 130 employees in 5 years.
Along the way, I made every hiring mistake possible. This framework is what I learned.
Part 1: The True Cost of Bad Hiring
Most founders underestimate this by 10x.
The Math Everyone Ignores
Timeline of a bad hire:
Month 1-2: Onboarding (you can’t evaluate yet)
Month 3: Something feels off, but you give them time
Month 4-5: Performance isn’t improving, but “maybe next quarter”
Month 6: You finally admit it’s not working
Month 7: Notice period, transition
Month 8-10: Recruiting replacement
Month 11-12: New hire starts, onboarding begins
Total time lost: 12-18 months
The Real Costs
Direct costs:
Salary: €60K-120K+ (depending on role)
Recruiting fees: €15K-30K (per hire × 2)
Onboarding time: 40-80 hours of senior team time
Hidden costs:
Lost momentum on strategic initiatives
Team morale damage (everyone knows before you admit it)
Customer relationships affected
Other team members compensating for underperformance
Opportunity cost (what you could have built instead)
Total real cost: €200K-500K per bad senior hire
But here’s what really hurts: You can’t buy back the time.
That 18 months at a startup?
That could have been the difference between market leadership and playing catch-up.
Part 2: The Mindset Shift
From “We need someone” to “We need the right someone”
Bad founders hire when desperate. Good founders hire when ready.
The 10-Candidate Rule
Never hire until you’ve interviewed at least 10 qualified candidates for the role.
Why?
Because candidate #3 always looks amazing compared to candidates #1 and #2.
But candidate #3 might be mediocre compared to candidates #8 and #9.
You need comparison data.
The “Top 5%” Standard
Our goal was always: Hire the top 5% for every role.
But here’s what that actually means:
NOT:
Top 5% in university grades
Top 5% in years of experience
Top 5% in previous company prestige
YES:
Top 5% in drive and execution speed
Top 5% in ownership mentality
Top 5% in growth mindset
The person who was average at Google but has the hunger to prove themselves at a startup?
That’s often better than the star performer who wants to coast.
Part 3: The 7 Deadly Hiring Mistakes
Mistake #1: Hiring because they’re “nice and cool”
This was my most frequent mistake.
“They’d be fun to grab a beer with” is not a hiring criterion.
Cultural fit matters. But “nice and cool” is table stakes, not the decision factor.
The fix: Ask yourself: “If this person was difficult to work with but delivered exceptional results, would I still want them?”
If the answer is yes, you’re evaluating on the right criteria. If the answer is no, you might be optimizing for friendship over performance.
Mistake #2: Hiring from big corporations
This was an almost-always-wrong pattern for us.
Someone who spent 5 years at Siemens, SAP, or BMW rarely worked out.
Why?
They’re conditioned for a different environment:
Clear processes vs. figuring it out
Specialized roles vs. wearing multiple hats
9-to-5 culture vs. “whatever it takes”
Low-risk decisions vs. high-risk/high-reward
The exceptions:
They left the corporate within 2 years (still had startup mindset)
They were frustrated by corporate slowness (actively seeking chaos)
They had side projects that showed entrepreneurial drive
Mistake #3: Hiring under urgency
“We need someone NOW” is how you make bad decisions.
The pressure scenarios:
Key person just quit
Customer needs escalating
Investor asking about org chart
Product launch deadline looming
The bad decision: You hire the first acceptable candidate instead of the best available candidate.
The fix: Build a talent pipeline BEFORE you need it.
Always be talking to great people, even when you’re not hiring. When a role opens up, you have 5 people you can call immediately.
Mistake #4: Skipping reference checks
Early on, I’d skip this if I “felt good” about the candidate.
Bad idea.
Why reference checks matter:
Verification: Is what they said actually true?
Pattern detection: Do multiple references say the same things?
Red flags: What are they NOT saying?
How to do them right:
Don’t just call the references they provided. Those are obviously curated.
Ask: “Who else should I talk to who worked closely with [candidate]?”
Then call those people.
Ask specific questions:
“How would you rate their performance 1-10? Why not higher?”
“What was their biggest weakness?”
“Would you hire them again?”
“What type of environment do they thrive in?”
The reference who pauses before answering “Would you hire them again?” is telling you everything.
Mistake #5: Not testing the skillset
Never hire based on resume and conversation alone.
Always include a work simulation.
For different roles:
Engineers:
Take-home project (4-6 hours, can be paid)
Code review session
Architecture discussion
Salespeople:
Mock pitch to your team
Discovery call role-play
Deal analysis exercise
Marketers:
Campaign strategy presentation
Content creation sample
Channel analysis
Designers:
Design critique session
Product improvement exercise
Portfolio deep-dive
The work sample reveals what 5 interviews never will.
Mistake #6: Hiring without multiple opinions
I made solo hiring decisions exactly twice.
Both were disasters.
The multi-stage process:
Round 1 - Screening (30 min): Hiring manager checks basics
Round 2 - Deep dive (60-90 min): Hiring manager evaluates skills, experience, fit
Round 3 - Work sample: Real work simulation
Round 4 - Team fit (45 min): 2-3 team members evaluate collaboration style
Round 5 - Values/culture (30 min): Founder or senior leader evaluates alignment
Critical: Different interviewers ask different questions. No redundancy.
Split the evaluation:
Person A: Technical skills and experience
Person B: Problem-solving and learning ability
Person C: Communication and collaboration
Person D: Values and motivation
After each round: Independent written feedback before discussing.
This prevents groupthink.
Mistake #7: Hiring when you have doubts
This is the most expensive mistake.
If you have ANY doubt after the process, the answer is no.
The rationalizations I used:
“Maybe they’ll grow into it”
“We can coach them up”
“They’re 80% there, close enough”
“We need someone now”
“They might be great despite the concern”
The reality:
The doubt you have in the interview gets bigger, not smaller, after they start.
The rule:
If you’re not actively excited about hiring this person, don’t hire them.
“Maybe” means no.
