Results 'somewhat accurate'
One had a change of heart, while others had their own ideas confirmed when they took the free Peaks Personality, Career and Subject profiling assessment at the Career & Education 2015 exhibition on Thursday.
They included secondary school students, school-leavers, university students and mid-career adults.
Said Damian Netto, 15, a Secondary 4 student at Whitley Secondary School:"I thought of being an accountant but the results of my test are all science-related.
"I'm not the best at science, but maybe that's because I don't pay much attention in class. I'll definitely pay more attention in science class after this. It may be an indicator that I'm actually good at science."
A 39-year-old woman, who wanted to be known only as Ms Teo, said: "I know myself pretty well already."
Ms Teo, an education recruitment consultant who specialises in sales and marketing, added: "Consultant administration, sales and marketing came up top on my list, which wasn't surprising. I guess now it's up to me to decide if I want to continue in this field or not."
Mr Vivek Menon, 26, a final-year mechanical engineering student at Nanyang Technological University, said he was taking the assessment for the second time, after first taking it in March 2012.
"I just want to see if it's really accurate and if I've changed over the years. The results were pretty much the same."
Mr Menon said: "The profiling also serves as a toolkit for interviews. Employers usually want to know what your strengths and weaknesses are, and the test helps to identify those."
However, some felt that the assessment should not be used as a sole determiner of one's dream job, even if it is able to reflect one's personality rather accurately.
Former Hwa Chong Institution student Kang Jia Rui, 19, who is waiting to enter university after finishing her A levels, said: "I came here hoping it would help me decide what university courses I should take.
"The results of my test were somewhat accurate, but I think we should still take the test with a pinch of salt and use it only as a guide."
