Career challenges
Short multiple-choice and scenario quizzes on the topics candidates search for most - pass odds, pay intuition, frontend level, mistakes, and job-market readiness.
Data structures & Big O interview test
Asymptotics, common structures, and the vocabulary coding screens still need.
HTTP, HTTPS & networking interview test
TLS, DNS, cookies, and the request path teams still whiteboard in full-stack roles.
Web app security (OWASP-style) test
Injection, authn/authz, and the failures interviewers list first.
Agile, Scrum & communication test
Estimates, commitments, and cross-functional clarity in real delivery (not certificate trivia).
DevOps & CI/CD basics test
Pipelines, rollbacks, and operability-what SRE/Platform/Backend screens often touch.
ML interview signals (non-research) test
Train/val/test, leakage, and production realism-what “applied ML” screens usually mean.
