I applied to Staff Scientist position and was contacted by an ALL4 recruiter to "begin the interview process". I completed their pre-screening questionnaire (9 science based math problems) and the situational expressions (8 situation based questions) which took a few hours. After submission, I waited two weeks and had to reach out to the recruiter to find out my application status which led to me getting pushed along. I was then asked to complete a sample project. The project took four hours to complete and was scheduled during the middle of a work day. After submitting this portion of the "interview process", I waited another week without hearing from the recruiter. After reaching out again, I was told to hold tight and that I would be hearing about my status soon. I am now writing this a month and a half later after not hearing anything back. I did not appreciate their process of having me put in seven quality hours of my time (four hours taken off of work) to not even receive a simple email notifying me that I was not their selection. I understand that not every candidate can receive the job but I feel that it was a very unprofessional way of handling the process.
