Re: SJSU
SJSU is also not overlooked by prospective CS majors applying to colleges. CS is the most selective major there – frosh admission threshold HS GPA (CSU recalculated with limited weighting) is typically in the 4.3 range (close to the maximum possible), even though most other majors’ frosh admission thresholds are in the 2.5-3.0 range.
However, CodeSignal’s claim that its General Coding Assessment is “Completed by 3 out of 4 Computer Science students in the US” does not seem to be very believable. I have never heard of it, much less been at a company that used it in the hiring process (for new graduates, or anyone). Nor have I heard of it being used as part of CS major curricula in college.
If it is as widespread as CodeSignal claims it is, it would not be surprising if some students were studying and practicing specifically for the test (like with any standardized test) and/or some CS departments embedded practicing specifically for the test in some of the CS courses.
