Adaptive interview prep and mentorship for experienced software engineers
Practice recalibrates each session, getting harder as you improve so hours go where your target rounds demand.
Get matched with mentors and hiring managers who run interviews at the companies you're targeting.
Prepare for data structures and algorithms, system design, AI-assisted coding, behavioral rounds, and more.
Solo, one-on-one, or small-group mocks plus career coaching and negotiation support.
Undetectable AI assistant for live technical interviews
The assistant transcribes the question as it is asked and returns a working solution you can read from the overlay, aimed at LeetCode-style prompts.
Captures and transcribes the interviewer's speech so the AI can follow questions delivered verbally during the call.
The window stays out of screen shares, dock, taskbar and the activity monitor, with click-through behaviour and a disguised process name.
Targets coding, system design, behavioural, full-stack, data, AI/ML, consulting, trading and product interviews rather than only algorithms.
