IMHO trying to educate companies about their process is a sure way to failure.
Also doing interviews before technical challenge is a sure suicide for companies. In my experience to minimise the waste of time you send out quick and easy technical challenge (no more than 30 minutes!) and you filter out 90% of applicants.
With remaining 10% you have a phone call and if you have more than X (magic number of 3 in my experience) of qualified applicants you send out more thorough tech challenge (no more than 2h long!).
Rinse and repeat until you get to X applicants which you will invite for face to face interview.
Truth is that almost no-one in tech is qualified to do face-to-face interviews. Either they are not on the level technically or dont have the communication and HR skills. Interview in person is mostly to see if you are not dealing with a weirdo and if that person will be a good fit for the team.
A side note, I tend to issue valuable response to every candidate. If you do that, they are very likely to re-apply, step up when someone drops out or recommend to friends. People tend to do/say the same dumm stuff so you can prepare those replies as well.
