Recruiter reached out asking about the experience. Provided all the information, Scheduled interviews in a few weeks starting with OA.
Cut to OA date and I had three easy questions
Q1 - Find the number of valid times of HH:MM format given four integers A,B,C,D.
Example - A = 1 B = 2 C = 3 D = 4
Answer - 10
Possible valid combinations are - {\'12:43\', \'21:43\', \'13:42\', \'14:32\', \'21:34\', \'23:14\', \'13:24\', \'12:34\', \'14:23\', \'23:41\'}
I wrote a brute force solution since input size is small and constant and believe its a O(1) solution, not sure if that will be penalized. Invalid combinations are - 43:21, 34:12 etc.
Q2 - question related to arrays but dont remember well, but was easy
Q3 - Finding minimum number of steps to get to a goal number given start and end target number. You can rotate any digit of the number in forward direction for each digit to reach next state.
Result Awaiting.
