There are a total of 4 to 5 rounds.

After clearing my first round on DSA and algorithms, the second round experience was the worst. The interviewer was very rude; it seemed he had already decided to reject me and was trying to show off his knowledge.

In the second round, the interviewer directly rejected my solution without going through the code I had written. When I asked why, he claimed the assigned boolean array would have garbage values (he didn't know that the default value is false when a boolean array is initialized in Java). I then explained that it doesn't contain garbage values. After that, he stated I had some duplicate conditions in the base case, and I explained where they were necessary.

It seemed like he had opened a pre-existing solution on his laptop and was expecting the same. Because of this, he wasn't trying to understand my code logic and algorithm.

I was surprised that in a well-established organization, at higher positions, there are people like this.

Basic array and matrix questions.

Find the count of the highest filled color which has parallel cells in the grid. (Similar to finding the size of the largest islands in a matrix).
