Cracking an interview can be a difficult task, especially in these times when there is a cut throat competition in the job market, after having interviewed heavily for Machine Learning and Data Science roles at big companies and startups, I have compiled a detailed list of Data Science Interview Resources, which I can assure will prepare you very well for an upcoming Data Science/ML Interview. And I update the list frequently with hand-picked quality resources, which you can use to prepare for your interviews! Best of luck!

O(f(n))
on the left might be referring to Big-O notation, but I'm not sure if you're working in that space of work. But even so within Big-O notation, I'm not sure what the lowercase O is referring to. What area of work is this equation showing up in?
f(n)
(O(f(n))
) is equivalent to f(n)
itself. This might make sense in the right context, but right here, it kinda doesn't mean much. I hope the notation explanation can lead you to the right direction. You can read more about time complexities here https://en.wikipedia.org/wiki/Time_complexity#Table_of_common_time_complexities
