The customer service profile has 140 prompts and no clock, and it checks whether you answer consistently

Some call center employers add a short cognitive test to the profile and typing checks. Our Wonderlic-style test trains quick vocabulary, simple math and following instructions under a clock, which is the closest practice we have for that kind of screen.

The core customer service tools are a personality profile with no right answers, a typing test and call or chat simulations. We imitate none of them. Our free test helps only if your invitation includes a timed reasoning part.

Criteria says its Customer Service Aptitude Profile contains 140 prompts and measures cooperativeness, personal diplomacy, patience, relaxed attitude and achievement. Its score report guide describes an Inconsistent Responding scale: if a candidate scores 3 or higher, the report shows several warnings to the employer.

That makes trying to game the profile risky. A consistency scale compares your answers across the whole profile, so answering one way when it sounds good and another way later is the pattern it exists to catch. Read each prompt, answer as you behave at work on a normal day, and keep going.

The CSAP is untimed, and Criteria says most candidates finish in about 10 minutes. With 140 prompts, that is a few seconds each. Your first honest reaction is usually your most consistent answer.

Overthinking tends to produce more neutral answers and more contradictions. Pick a quiet time, avoid long breaks in the middle, and do not go back to change earlier answers to match how you think you should look.

Most call centers and outsourcing firms include a typing test, and one practice source puts the usual length at 3 to 5 minutes, with some employers using a one-minute screen and others ten minutes. eSkill sells a call center typing test built on a call center paragraph.

Many typing tests report an error-adjusted speed, so a burst of fast, sloppy typing can score worse than a steady pace. Practise on short customer-style paragraphs, with names, numbers and addresses, and correct as you go.

SHL describes a contact center call simulation that measures how you handle customer concerns on a call by referring to standard process documents, and also measures typing and documentation. Vendors such as eSkill sell call center simulations of the same kind, and some vendors now use live chat simulations instead of plain typing tests.

In a simulation, listen for what the customer actually wants, find the matching step in the documents you are given, and record details exactly. Accuracy of the account number or address you enter usually counts as much as tone.

Some employers add a short cognitive test, such as a Criteria or Wonderlic test, to the profile. If yours does, it will arrive as a timed set of verbal, math and logic items. Criteria's CCAT, for example, is 50 questions in 15 minutes, more than most people finish.

Our Criteria tests overview explains which Criteria tests employers combine, and our Wonderlic practice test gives you a timed run of that style. If the invitation names the CCAT, use our CCAT practice test instead.

These come from anonymous reviews, university careers pages and prep guides. They often disagree, and Customer service and call center has not confirmed them. Read them as leads, not rules.

• One practice site reports that most call center typing tests last 3 to 5 minutes.
• One assessment vendor describes an audio-based call center test of about 25 questions in about 15 minutes.
• Vendor blogs argue that simulations predict call center performance better than raw typing speed.
