Rehearsed answers pass non-technical screens and AI tools. They don’t pass a conversation with an engineer who knows where to dig.
I’m that engineer, and I give you a judgement you can trust.

How I interview
I don’t fire random questions or check whether candidates guessed the answer I had in mind. I watch how they think: how they explain decisions, ask clarifying questions and handle a task that isn’t fully defined. Every interview is recorded, so everything in the report rests on what the candidate actually said. I run no more than two interviews a day, so every candidate gets my full attention.
Why me
15+ years in web development, most recently Senior Software Engineer at DataRobot.
10+ years of technical interviews, including paid consulting for companies as an independent interviewer.
40+ public technical interviews and test-assignment reviews on YouTube; two in English.
What you get
A role profile agreed with the hiring manager: must-haves, nice-to-haves, red flags.
A 60–90 minute structured interview with each candidate, on a call you host and record.
A written assessment within 48 hours: whether the candidate passed the technical interview, level, scorecard against the must-haves, strengths and concerns. The hiring decision stays with you.
I cover frontend roles in full, Trainee to Tech Lead, and the non-stack side of senior roles in any stack. Sample reports on request. For agencies, reports go out under the agency’s name.
Price
$200 per interview for Junior to Middle, $260 for Senior to Lead, plus $240 per role for the role profile and interview plan, waived from the third candidate on the same role. No retainer or minimum.
Your first role can run hourly at $80, so you can judge the report before committing to more.
Add-ons, cancellations and payment terms are in the service details (PDF).
