Codeaid
Coding assessments and an AI interviewer built for hiring AI and machine-learning engineers, from $129/mo with a 14-day trial.
From $129/mo 14-day free trial
Bottom line
A coding assessment platform built specifically for AI and machine-learning roles. Candidates work in real notebooks or GPU containers on messy datasets, and an AI interviewer builds the test and scores the work. The Team plan is $129/mo for 20 candidate invites a month, with a 14-day free trial.
Stands out for: General coding test platforms struggle to tell whether someone can actually train and debug a model. Codeaid tests that directly, with datasets too large to paste into an AI assistant, and agencies can use it to pre-screen ML candidates before sending them to clients.
Watch out for: Twenty invites a month on the Team plan is tight for volume hiring, so credit packs or Enterprise may be needed. It is narrow by design: for general software engineering or non-technical roles a broader assessment library fits better.
Overview
Codeaid is an assessment platform for evaluating AI and machine-learning engineers, used both for hiring and for checking the skills of existing teams. Tests cover traditional ML, deep learning, generative AI, NLP and computer vision, and can include agent frameworks such as LangChain and AutoGen.
Candidates work in a simulated job environment, either JupyterLite notebooks or GPU-powered containers, on large, messy datasets. Codeaid says the datasets are too big to feed into an AI tool, so results reflect the candidate's own work.
The AI interviewer helps you build an assessment from your requirements or a template, sets difficulty and question types, and runs 24/7 so no live technical interview needs scheduling. Reports cover code quality, model performance, problem-solving approach and engineering decisions.
The Team plan costs $129/mo (20% less billed annually) for 5 users and 20 candidate invites a month, with Greenhouse, SmartRecruiters and Recruitee integrations and a 14-day free trial. Enterprise is quoted.
