First of all I'd question where did your lecturer get the stats from, second of all that lecturer of yours should reconsider their choice of career as they definitely don't know how to develop and support students. Gosh imagine being a lecturer and telling your students that 99% of them will fail, ffs.
Although that stat does not surprise me, but you have to remember a few things before getting anxious about all that:
- At least half of the applicants (if not more) are absolutely not suitable for the job, they either have horrendous CVs or perform poorly on the interviews. If you spend at least a few hours on your CV and tailor it to every job you apply you're already better than half of the applicants. If you then prepare well for the interview then you're already in the 1% easily. Considering you're technically knowledgeable in your field of course, that's a given, however as I said many applicants would lie on their CV and then miserably fail on the interview. I've interviewed some of those guys, quite an awkward experience both for the interviewer and for the interviewee.
- The 1% is probably an overall statistics or is leaning towards experience you may have applying for the most known and reputable companies (say PwC, Deloitte, EY and KPMG). Those companies receive hundreds if not thousands of applications per position every year. Out of those, as I mentioned earlier, the hiring manager may look through 30 or 50 CVs that at least meet the job requirement simply because the rest of the applications are either non relevant or are complete garbage. That's where AI filtering and HR recruiters comes in place to separate decent candidates from the rest of the crowd. Hiring manager will not be physically able to look through such an amount.
If you apply to smaller companies you may compete against less than a dozen or two of candidates during the initial screening stage.
- Remember that you can play this statistics game to increase your odds by increasing the quality of your applications and by applying to as many places as you can, without compromising the quality of the application.
That comes from someone who went through dozens of applications and interviews and who's been involved in recruitment for interns and graduates later in my life, so I have some real world data to back this up.
All the best!
