Hi Alex,

Hope you are well.

Congratulations for getting invited for PST / Imbellus test. This means you have successfully passed the CV screening phase, which is a significant hurdle in itself.

To answer your questions:
1) I believe this is not the case. Getting invited over a PST means you have already passed the CV screening. Given the very large pool of McKinsey prospective candidates who goes through CV screening and PST, the HR team would unlikely have the team to categorize the profiles in terms of priorities, unless for a clearly distinctive ones.

Even considering this, the fact that you have been invited to sit on the PST within a very short timeframe previously would actually indicates you are on the priority pool.

What causes the delay is the rescheduling request you have asked to the team. Again, mind that there are enormous number of profiles going through CV screening and PST. If one profile cannot attend a session, they would still need to process the other profiles waiting on the pipeline, hence the profile that requested rescheduling, will need to be pushed to the back.

This action in effect displayed meritocractic traits of the Firm, where they treat everyone equally at the PST stage. Rescheduling of one profile should not mean pushing back the long array of other profiles on the queue.

2) Yes, you will. The HR team had to process a great number of profiles on the pipeline, hence delays for rescheduling is to be expected. Also, it is completely fine to follow-up and remind them occassionally, as it would serve as a reminder to them and easen up their workload. Since it has been 3 weeks, reaching out to them at once is advisable.

3) I do know a number of prospective candidates and Firm members who experienced similar situation in the recruitment process.

Fingers crossed you will get a confirmation on the test soon.
Hope it helps.

Kind regards,
Nathan
