When it comes to aptitude tests there is no pass mark which goes for everything. There are three main reasons behind this: first of all, the aptitude test scores are generally rated against the average of other people applying to the same position. This means every single recruitment round will have different averages. Also, drawing a generic pass mark becomes impossible due to the vast variety of aptitude tests companies are fielding these days. There are so many to choose from starting from brand to type within each brand.
Not only aptitude tests are different, many of them have markedly different difficulties. Most of the time, you will only know which test you will be taking once the company invites you to take a certain test after the initial interview round. The type and thus difficulty of your test depends on what job you are seeking and the company you are applying for.
Some aptitude test providers make very hard tests, while others will stick to more traditional, easy and commonly recognizable tests which are not as hard or intensive. Examples of medium difficulty tests include the ones provided by SHL, Kenexa, Saville and TalentLens. Compared to other alternatives, you may say these are ‘easy’. The hardest tests you can face are commonly created by three different companies. Cubiks and TalentQ will put a lot of pressure on you due to the complexity of problems and unique time limit set per question. Cut-e (test service company) goes for a different approach. Cut-e tests are extremely time limited, to the point where simply cannot answer all the questions given within the time frame. Prospective employers know that and will consider your results accordingly.
The hard road
Cubiks and TalentQ are particularly hard and known for it because of how intense they are and the amount of tests they throw upon an applicant. When going up to face any of these two you need to be prepared to face many more tests within tests, endless questions and much more than the usual triad verbal, logical and numerical reasoning questions which are usually found in the average aptitude test. For Cubiks and TalentQ, not only you need to be prepared to answer the questions and to solve the problems presented to you, you also need to be mentally and physically conditioned for a very draining and restless period because unlike Cut-e, the time limit to answer each and every question is standard, giving the applicant enough time to think. When you look at the amount of questions and problems each test has, you will need your brain fresh to work at its full capacity.
The impossible task
In Cut-e numerical reasoning format you are given 12 minutes to answer 37 questions and no one expects you to do all of it, however, your results will be judged against how much other applicants got done correctly. In the end the question is why do this at all, but when you are getting hired you get extreme questions thrown at you to see how you can withstand tension and pressure at the workplace.
Regardless of the test, even if they have no specific pass mark that does not in any way mean that aptitude tests are a walk in the park or that any mark will do. That is simply not the case, and a careless attitude never got anyone hired. It is your job not only to prepare, but to do so accordingly to the type of test you will be facing. Fortunately you can find plenty information online depending on which test you will be taking, and you can take free tests which allow you to explore the format and get plenty of preparation.
