Result: Selected

Difficulty: Medium

Rounds: 2 rounds

Topics Asked: Data Structures, Algorithms (Bitwise XOR, Integer Division), Basic HR Questions.

Experience:

This candidate, a Computer Science Engineering student from MIET college, successfully cleared two rounds for an SDE-1 position. The preparation involved studying Data Structures and Algorithms for about 6 months.

Round 1: Technical/Coding Round
This round included coding problems. One specific problem mentioned was:

• An array 'ARR' consists of 'N' numbers. The task is to find a pair having the minimum XOR value. No need to print the values of the elements, just print the minimum XOR value.

Round 2: Technical/Coding Round
This round also featured coding problems. A problem related to integer division was mentioned:

• Implement integer division without using multiplication, division, or modulo operators. In cases where the dividend is not perfectly divisible by the divisor, return the integer value of the quotient closer to zero. Handle 32-bit signed integer range limits by returning `2^31 - 1` if the quotient is too high, and `-2^31` if it is too low.

In total, 6 coding problems were discussed across the two rounds. The candidate was selected.
