Utterly ridiculous.
First there was a face to face interview at a coffee shop that took about an hour.
Next, I had fill out an insane amount of questionnaires, work history, academic history, provide multiple letters of recommendations, transcipts, write practically an autobiography as well as some passionate essay about why I wanted to teach disadvantaged children, pass an extensive background check, and more that slips my mind.
Then there was a one on one web interview, also took around an hour, and then we had a multi panel interview, with several interviewees and interviewers to "compete" with, followed by another one on one again all of which took several hours.
By the end of it I decided this was insane and if they are having these asks up front from a candidate I didn't want to know what actually working for them would be like.
The whole thing reeked of a scam/exploitation. I understand it is a legitimate company, but they basically come out and say you will be over worked and under paid.
