four rounds of interviews, each lasting 45 minutes. It is crucial not to delay. In the first round, the candidate seemed to struggle with a bucket sort problem involving sorting 1 million numbers. He was expected to create an array to track the occurrence of each number and then return a new array.
In the second round, the candidate was asked to find any duplicate number within a set of numbers efficiently. Despite not initially realizing the need to return a value, the candidate proposed three methods, all of which were rejected.
The third round involved a stock trading problem, which was quite similar to a common question about buying and selling stocks once, with buying before selling.
In the fourth round, the candidate had difficulty understanding the task given by the interviewer, who seemed to be from India. The task involved creating a tree-like data structure based on a given class.
Overall, the performance was good, but no offer was extended. The candidate struggled to get into the right mindset in the first round and had difficulty understanding the task in the fourth round.
