First, to clarify, I have previously tutored Stanford PHD students and have done native IOS programming in Objective C and every version of Swift. I also do full stack Unity AR/VR in C# and have programmed in numerous other languages.

Have been going through the Codility lesson "tasks" to prepare for a coding interview...which has not been fun and has not seemed very reasonable.

Sometimes, although the algo I wrote passed the test cases, the "correctness" and "performance" test have been tough. Basically there is a lot of ambiguity in the requirements in the overview of the algo request and then some of the edge cases that are input into the algo have been really unexpected. Plus the Codility pages don't really show very clearly what the input was.

I have seen example coding interviews at Google that are SOOOOOOO much easier than what I have done and have been asked to do on Codility.

Thus, basically, once I am hitting 100 percent on every Codility test, it seems as though I would be considered skilled enough at writing algorithms to be a senior level programmer at any company.

I say that partially because I wasn't planning on rushing to senior level programming level. Already a little tired of sprinting up flights of levels of difficulty after years of learning and doing native IOS programming.

So, is that basically the situation? Does completing every algo at 100 percent on Codility basically say that a programmer is generally at senior level in algorithm programming?

Thanks in advance for productive answers.
