Payme interview process

Common questions at Payme

• 1.Briefly tell us about yourself and your experience.
• 2.Tell us about some interesting projects you have worked on.
• 3.Task 1 — Card expiry parser. Write a function that takes a card expiry date as a string and returns it normalised as year then month. The input may arrive in either order (month first or year first) and may contain noise characters, because it is read from a camera scan. Filter out everything that is not a digit and handle all edge cases. You cannot run or debug the code.
• 4.Given the input 1111, how do you know which part is the year and which is the month?
• 5.What about 0100 — which part is the year there, and why does your code decide that?
• 6.What does split() return?
• 7.Now rewrite that parsing logic using array methods instead of manual indexing.
• 8.What happens if the input contains extra symbols? How many characters in this input satisfy your filter condition?
• 9.Task 2 — Time difference formatter. Write a function that takes two numbers, both in milliseconds, and returns a string describing the time elapsed between them, formatted as minutes and seconds with zero padding.
• 10.Is it a problem that you run that many loops? Do you know O-notation?
• 11.How do you determine the time complexity of your solution?
• 12.What is the point of these loops — what do they do, and why do you need them?
