Asked in companies
You are given an array, ‘COORDINATES’ that represents the integer coordinates of some points on a 2D plane. Your task is to find the minimum cost to make all the points connected where the cost of connecting two points: (x1, y1) and (x2, y2) is equal to the manhattan distance between them, i.e., |x1 - x2| + |y1 - y2|.
Note:
1) An element of the ‘COORDINATES’ array is a pair of ‘X' and ‘Y’ coordinates of a point, i.e., COORDINATES[i] = (Xi, Yi).
2) |DISTANCE| represents the absolute value of distance.
3) All points are considered to be connected if there is exactly one simple path between two points.
4) According to Wikipedia, a simple path is a path in a plane that does not have repeating points.

The interview lasts for approx 60 minutes. It takes place at about 1:00 in the afternoon. Both technical and the HR round take place in the same interview. The technical questions were mainly from the oops concepts, data structure, DBMS and algorithm, and mainly resume-based.
The HR questions were mainly about the company, willingness to reallocate, personal preference, why to join TCS, further plans etc.
There were 4 members in the panel and all were supportive and gave proper time to think about the solution. Two were for the technical round and 2 for the HR round.
