Blogvault Interview Experience (On-Campus 2020)

Round 1: It happened in Dec 2020.  Online coding round of 2 hours on Interviewbit platform, and three questions. Students who completed 2 questions or more were shortlisted for the interviews. The coding questions were: 

1. A number of subsequences of the form a^i b^j c^k.
2. Predicting whether traveling to treasure within a grid from the current position in k turns is true or not.
3. Choosing the 2 roads that need to be closed from M roads between N villages to ensure maximum kingdom happiness.

Round 2: Around 15 students reached this round. Through telephonic interview (and video chat for some), questions were asked regarding Sorts, puzzles, tree traversals, and string coding questions to achieve a certain outcome (reverse string, reverse each word of string, count all characters of the string and return each character with count) without using STL. Also, efficient solutions and the least complexity were appreciated. 

Round 3: Around 13 students reached this round. Through another telephonic interview, questions regarding puzzles, and coding solutions were asked. To me, the questions asked to be coded within a specific time frame were:

1. For a given array containing N elements and a given sum K, print all possible quad tuples for K.
2. Number of Islands from a given binary matrix

Round 4: 11 students reached this round. A coding environment was provided(coderpad.io). A string-based question with test cases was provided. We needed to code and run it for all test cases within 1 hour. Questions were asked on the logic used. Those whose maximum test cases ran successfully passed this round. The question was challenging and difficult. The language chosen for coding was highly influential in how your final code would turn out.

Round 5: 5 students reached this round. Was a short HR round regarding details about oneself.

Round 6: Continuing from R5, a rigorous talk on the code of the R4 round, and projects are done in college life took place with the founder of the company. The questions were pointed on every aspect of the projects.

Final Results: From the 5 candidates, 3 were selected for 6M+FTE, while 1 was selected for 6M.
