Why clients trust Proxify
"We can trust Proxify to select good engineers that can help us speed up the process."
"The candidates coming in from Proxify are top-notch individuals."
Only senior professionals, extensively vetted
Skip the resume pile. Our network represents the elite 1% of AWS S3 developers worldwide, across 1,000+ tech competencies, with an average of eight years of experience—meticulously vetted and instantly available.
Application process
Our vetting process is one of the most rigorous in the industry. Over 20,000 developers apply each month to join our network, but only about 1% make it through. When a candidate applies, they’re evaluated through our Applicant Tracking System. We consider factors like years of experience, tech stack, rates, location, and English proficiency.
Screening interview
The candidates meet with one of our recruiters for an intro interview. This is where we dig into their English proficiency, soft skills, technical abilities, motivation, rates, and availability. We also consider our supply-demand ratio for their specific skill set, adjusting our expectations based on how in-demand their skills are.
Assessment
Next up, the candidate receives an assessment; this test focuses on real-world coding challenges and bug fixing, with a time limit to assess how they perform under pressure. It’s designed to reflect the kind of work they’ll be doing with clients, ensuring they have the necessary expertise.
Live coding
Candidates who pass the assessment move on to a technical interview. This interview includes live coding exercises with our senior engineers, during which they're presented with problems and need to find the best solutions on the spot. It’s a deep dive into their technical skills, problem-solving abilities, and thinking through complex issues.
Proxify member
When the candidate impresses in all the previous steps, they’re invited to join the Proxify network.
"Quality is at the core of what we do. Our in-depth assessment process ensures that only the top 1% of developers join the Proxify network, so our clients always get the best talent available."
