Let’s explore how you handle distributed consensus under network partition. If 2 of your 5 Raft nodes lose heartbeat simultaneously during a write burst, walk me through the quorum election and log repair phase.
Elena Rostova
Since 3 nodes remain online, we still meet the majority quorum of 3/5 (floor(N/2)+1). The candidate leader in the majority partition increments the term, collects 3 RequestVote ACKs, and enters Leader state. When the partitioned nodes rejoin, their higher-term log reconciliation triggers AppendEntries with index back-propagation.

Frequently Asked Questions

Everything you need to know about the free platform. Straightforward answers, no jargon.

Legacy assessment platforms like Criteria Corp and TestGorilla rely on static multiple-choice questions or cookie-cutter LeetCode puzzles behind expensive annual enterprise contracts ($3,500–$15,000/yr) plus per-candidate test fees. SOLLERT provides an autonomous, adaptive AI vetting framework featuring live sandboxed code execution, anti-cheat telemetry, and 100-point explainable scorecards, completely free for solo recruiters and candidates worldwide.
Tools like Flowmingo.ai ask applicants to record one-way video monologues into a webcam, which candidates dislike and which fails to probe technical depth. SOLLERT conducts live, two-way adaptive technical dialogues and interactive coding sandboxes, dynamically generating intelligent follow-up questions tailored to the candidate's specific explanations.
Yes. SOLLERT is built for distributed, cross-border hiring with edge nodes operating worldwide. We support candidate evaluation in any timezone and benchmark compensation in multiple currencies (USD, EUR, GBP, CAD, AUD, SGD, and Global Remote parity). There are no country-specific restrictions or currency locks.
Yes, absolutely. The candidate portal is always free with zero paywalls. Applicants can take adaptive AI technical assessments, receive a verified 100-point scorecard credential, discover vetted requisitions matching their verified skills, explore global engineering salary trends, and receive personalized resume skill enhancement recommendations.
SOLLERT executes candidate code in an isolated WebAssembly/Docker sandbox and evaluates real-time keystroke cadences, paste heuristics, response latencies, tab switching telemetry, and syntactic authenticity with 99.9% precision, completely automated without invasive desktop screen recorders.
Solo recruiters and hiring teams receive unlimited job requisitions, unlimited autonomous AI candidate screenings, 100-point explainable rubrics, candidate Kanban pipeline management, and public job board hosting for free. Paid agency and team features (such as inviting multiple recruiter seats, agency client sharing, or custom engineering rubric imports) are accessible inside organization settings.
No. You can create an organization or candidate account in seconds using just your email. There is no credit card required, no trial expiration date, and no surprise paywall.
