Leadership hiring
It takes a CTO to hire a CTO
If you're hiring your next CTO or tech lead, their skills need to be on par. An external CTO can effectively identify and assess the right candidate for the job.

Trusted by talent teams and hiring managers
Working with AssessDev was inspiring. The quality of their interviews shone through in the detailed documentation we received. I recommend the AssessDev team to anyone who needs to assess technical profiles at a high level.
Our startup was hiring our first full-stack developer. We worked with AssessDev to come up with an interview guide, which we still follow. We feel much more confident interviewing, and we're happy to recommend AssessDev.
I want to share nice feedback from a candidate last week: this was the most pleasant interview I have ever had. Interviewer score: 10 out of 10.
Kat has been a trusted partner to us, providing high quality technical interviews and ensuring our hiring process remains extremely high quality. We also love the reports she prepares. Five star service.

Interview scopes
We assess on different stacks and skills
Full-Stack Tech Lead
We test anything from Python, Java, Ruby on Rails, and Django on the backend, to Node.js, Angular, Vue.js, React, and classic JS on the frontend.
Frontend & Mobile
We evaluate frontend and mobile developers, focused on React, React Native, Android with Java and Kotlin, plus the basics like CSS and Tailwind.
Backend & Database
We assess experience developing and scaling backends such as Ruby, Python, Django, Java, and Node.js, plus database systems like PostgreSQL and MongoDB.
DevOps & Cloud
From AWS, GCP, and Kubernetes to the fundamentals, we assess general DevOps, sysadmin, and networking skills and experience.
Data Science & AI
We test down to the basics: a candidate's real knowledge and skills with Python, machine learning, artificial intelligence, visualization, and data analysis.
Product & PM
A team of tech leads and startup founders is best placed to evaluate product thinking, design thinking, and project management beyond Scrum and kanban.
CTOs & Engineering Leaders
From CTO interviews to VP of Engineering evaluations, we assess technical leadership candidates on architecture judgment, team leadership, and strategic decisions, the calls only someone who's done the job can properly evaluate. See how we interview CTOs ➔
Software & Full-Stack Engineers
We interview software and full-stack engineers on real, hands-on coding ability, not resume keywords, testing how they design, debug, and reason through problems under realistic constraints.
LLM Engineers & AI Product Managers
AI hiring needs its own rubric. We assess LLM engineers on prompt engineering, RAG pipelines, and fine-tuning, and AI product managers on how well they scope, ship, and measure AI features that actually work in production.
Cloud Engineers
We evaluate cloud engineers on AWS, GCP, and Azure infrastructure, Kubernetes, and the cost and reliability tradeoffs that separate a working setup from a production-grade one.
Embedded Developers
Embedded systems interviews test a different skill set: C and C++, real-time constraints, hardware interfaces, and debugging without the safety net of a full stack trace.
Data Engineers & Data Scientists
We assess data engineers on pipeline design, ETL, and data infrastructure, and data scientists on statistical thinking, model evaluation, and turning results into decisions a business can act on.
