Q2. Basic frontend question like styling, dom manipulatiol etc.
Add your answer

It was a 3 hr long coding test, where 1-2 question may be asked based on scenarios, question will be medium level, but should pass all the test cases,

Q1. Was asked about the Dijkstra Algorithm and a counter-question based on that, later discussed on the resume.
Add your answer
Q2. Write the code for the Dijkstra
Ans. 
Dijkstra's algorithm finds the shortest path in a graph from a starting node to all other nodes.
• Use a priority queue to keep track of the shortest distance to each node

• Initialize distances to all nodes as infinity except the starting node as 0

• Iterate through all nodes and update distances if a shorter path is found

• Repeat until all nodes are visited and shortest paths are calculated

Q3. Dry run on a sample test.
Ans. 
Dry run on a sample test involves mentally executing the code to understand its flow and output.
• Understand the code logic and variables

• Step through each line of code

• Keep track of variable values at each step

• Predict the output based on the code execution

A standard aptitude test consisting of multiple-choice questions that needed to be completed within a specific time frame was administered. It has been four years, so I do not recall the details.

Samsung's coding test consists of solving a single complex question over a duration of four hours. The time complexity typically holds less significance; some questions can even be tackled with O(n^3) complexity. The emphasis is on our understanding of the problem statement and our approach to coding the solution. Since the solution tends to be quite extensive, requiring substantial code, optimization is not generally the primary focus. It is important to offer a reasonable solution. Topics such as graphs, binary search, and object-oriented programming are commonly featured in the test.

Q1. It was a technical discussion round. Usually Java & Android are a plus to have because Samsung focuses on it a lot. But, becasue I was experienced in Python, Django and Machine Learning instead, I asked i...read more
