There are a couple of pet peeves I've acquired while interviewing for a while, the first is about advice given to job seekers while the second is about tools used by recruiters.
Many boards, influencers and head hunters recommend customizing CVs for each application and to do background checks on the prospect companies. This would be good if it wasn't really time consuming and the probability of landing the job was high. On current state of affairs a job seeker will be doing hundredths of applications, I've done this, to even get to a human is probably around 1 in every 50 applications, to pass to the second round it is 1 on every 20 most likely and then depending on role and organization there might be two or three rounds of interviews which means a very low probability per submission. Each tweak to CV or org review will take at minimum 20 minutes and probably longer if done thoroughly. So imagine that a candidate is doing the updates for 100 positions, which is a very low number from my own experience, it would mean an investment of 33 hours. That is almost a full week of non stop work, anybody would be left exhausted and burnt out not to mention that looking out for a job is inherently stressful. It is economics of scale, unless you know you are a really good fit you do this updates and checks; unfortunately this is only true if you are being referred or you have prior knowledge of the organization. For me it is simply not doable.
The other one has to do with applicant tracking software or ATS for short. These tools are designed to help only the hiring part, from the joob seeker it is a real nightmare. I've seen simple ones that only ask for contact info and CV or ones that are already connected to linkedin or other work social networks, those are the best, but there are others that make me want to scream from the bottom of my lungs.
The most painful are the ones that require to re create the cv within the tool itself, others that are SaaS but make you create yet another account that you’ll never use again unless you get to the human interview, or worse it is the same application but for a different organization hence yet another user/password to confuse yourself as the only difference is a subdomain that is very easy to miss or worse a different path.
