I redid / resubmitted some questions I found hard from two weeks ago. My user activity tile page did not update with those submissions (tile did not turn green). After an accepted submission, does any further submissions on the same question not count as 'user activity'? Does it have to be on a new question which I have not submitted anything for?

I saw this blog https://codeforces.com/blog/entry/18417 and its been 6 years so thought I would post this and get updated opinions especially since interviews have gotten a lot harder recently.

I understand each interview is different and depends on the interviewer. What are your opinions? Datapoints are welcome! e.g. 'I can solve DIV2 A,B,C and I failed FB' or 'I am 1600 and I passed Google'.

Why am I asking this? It helps me to stay motivated and interested — hopefully it is helpful for others :)
