  • Who are we?

    Calibre is a new pre-employment assessment platform aimed at helping firms increase their recruitment efficiency and filter for the optimal candidates.

    Over the last few years, we have analysed the currently available testing services and conducted surveys with university students regarding their experiences with pre-employment assessments. The key conclusions we have found are:

    • Existing assessments are not designed well and are not visually engaging for candidates
    • Candidates become discouraged from applying for too many roles as they have to complete multiple sets of assessments for each application
    • Candidates have experienced repeated questions between employers, effectively making the filtration process redundant

    As a result, we founded Calibre, a new pre-employment assessment which will offer will offer both general aptitude (e.g. numerical, verbal, memory) and subject specific (e.g. programming aptitude, modelling, accounting principles) assessments which are interactive and visually-engaging. 

    We also ensure that applicants take the assessments multiple times to check for consistency and eliminate the element of luck. Applicants only have to complete these assessments every six months and can then submit the same scores to multiple firms saving time for both applicants and for employers. Our assessments also utilise computer adaptive testing along with an extensive question bank to prevent repetition of questions between candidates.
