In their own words
Testlify
Testlify is an AI-powered skills assessment and interviewing platform for hiring teams. Its library includes more than 3,500 validated tests across role-specific, cognitive, coding, language, and personality categories. Teams can create assessments with video, audio, coding, and situational-judgment questions. Interviews can be one-way or two-way and use video, audio, or chat, including conversational AI interviews. Testlify says it automatically evaluates video, audio, chat, and coding responses, while recruiters retain control of final hiring decisions. Proctoring options include full-screen enforcement, tab-switch and copy-paste detection, webcam snapshots, and IP or location checks. It lists more than 100 ATS and HR integrations, including Workday, SAP SuccessFactors, Lever, Greenhouse, and BambooHR, plus a REST API and event webhooks. Candidates can complete assessments in a modern browser on desktop, tablet, or mobile without installing software. The paid Standard plan costs $139 a month, billed $1,668/year, and includes 100 credits per year and three user seats. Unused credits expire at the billing-cycle end. A 7-day trial is listed; there is no free plan.
