Program logic, without a language
Pseudo-code & Programming Logic — 20 questions in 25 minutes on reading and tracing program logic: loops, conditions, accumulators, nested iteration, integer division, string handling, value-versus-reference on a simple copy, function composition, a bug-spotting trace, and concept checks on FIFO and linear time. Language-agnostic — no syntax knowledge required, only the ability to execute logic in your head. Every traced answer in the bank was verified by running equivalent code.
Reading the documents engineers actually misread
Technical Reading Comprehension — 16 questions in 24 minutes on a product manual, an API changelog and an SOP, probed for conditions, exceptions, deadlines and precedence, plus compliance checks against specs, config rules, release notes and warranty clauses. Every answer is decidable strictly from the text, which is the point: the failure mode being measured is the assumption, not the vocabulary.
Executing a process exactly as specified
Flowcharts & Process Logic — 18 questions in 22 minutes tracing two realistic multi-branch flows under different inputs, plus loops with exit conditions, retry counting, decision tables, parallel-path durations, dependency ordering and escalation timing. This is the competency behind on-call runbooks, deployment checklists and anything automated.
Deduction, including the refusal to conclude
Deductive Logic & Syllogisms — 22 questions in 20 minutes: categorical syllogisms, modus ponens and modus tollens with the invalid forms most people fall for, disjunctive elimination, chained implications, contrapositive versus converse versus inverse. Several items are keyed to "may or may not", so the discipline of refusing an unwarranted conclusion is itself scored — which is exactly the habit you want in someone reading an incident timeline.
Data and digital fundamentals
Spreadsheet & Data Literacy (20 questions, 22 minutes — absolute references, IF/COUNTIF/VLOOKUP semantics, format-versus-value, the single-column sort disaster, median-versus-mean under outliers, truncated axes, CSV and mixed units) and Computer & Digital Fundamentals (25 questions, 18 minutes — files and formats, cloud concepts, networks and IP, plus a security block on passwords, phishing, 2FA, HTTPS and ransomware backups).
Judgement, escalation and ownership
Workplace Judgment — 16 realistic scenarios in 25 minutes: errors already sent to a client, conflicting senior instructions, confidential data exposed, impossible deadlines, scope creep, Friday-evening discoveries. Scored with graded partial credit, so a plausible-but-suboptimal response earns partial marks and the test separates sound judgement from merely avoiding the obviously wrong answer.
Working English, written and spoken
Written accuracy, register, concision and comprehension, plus AI-scored speaking and listening from the candidate's own recorded voice — a task no chatbot can sit for them. For a distributed engineering team English is not a nice-to-have; it is the medium the entire job happens in, and "fluent" on a profile becomes a score you can set a bar against.
Proctoring whose evidence you can open
Identity-baseline photo at the start, face-presence and additional-face monitoring, tab-switch, paste and screen-capture counters, and a High/Medium/Low integrity band computed from the published weights above — with the underlying evidence attached to the attempt rather than summarised away. A band you cannot inspect is just another claim.
One link, any phone, no accounts
Delivery is a share link or a QR code. Candidates create no account and need no card, the player is mobile-ready and resumable when a connection drops, and results rank the moment each person submits. That is what makes screening practical across Lagos, Nairobi and Cape Town without scheduling a single call.
