I live in western Europe. I've worked for 4 different companies, for European salaries, without doing any leetcode type interviews I ditched any company that was doing it , it was either take home tests about real problems, technical questions, or sometimes just trust in my abilities given my previous experiences. Do you think grinding leetcode is an absolute necessity to land a good job at a company hiring worldwide remotely? Thanks for your answers. Depends please give more details in comments. I believe leetcode is a way to skirt around discriminatory hiring practices.

Irrelevant - a CIO's job isn't to be a hands-on coder, it's to set a strategy and manage an organization. We need a credential that counts as passing a technical interview, m coloring problem leetcode, so we don't have to take these tests for every single job that we apply to. One implementation with a vendor required socket programming.

Given an undirected graph and a number m , the task is to color the given graph with at most m colors such that no two adjacent vertices of the graph are colored with the same color. Note: Here coloring of a graph means the assignment of colors to all vertices. Below is an example of a graph that can be colored with 3 different colors:. Output: Solution does not exist Explanation: No solution exits. Generate all possible configurations of colors. Since each node can be colored using any of the m available colors, the total number of color configurations possible is m V.

Graph coloring refers to the problem of coloring vertices of a graph in such a way that no two adjacent vertices have the same color. This is also called the vertex coloring problem. If coloring is done using at most m colors, it is called m-coloring. The minimum number of colors needed to color a graph is called its chromatic number. For example, the following can be colored a minimum of 2 colors. The problem of finding a chromatic number of a given graph is NP-complete.

In the M-Coloring problem , our task is to find if it is possible to assign nodes of a given graph with m different colors, such that no two adjacent vertices of the graph are of the same colors. If a solution exists, then display which color is assigned to each vertex. The m-coloring problem is practically used to solve problems like clustering, scheduling, job allocation problems and many more. The backtracking algorithm can be used to solve the m-coloring problem for the above graph. This algorithm will return which node will be assigned with which color.

My own experience when I fail to think of an answer to a leetcode question is extremely similar if not identical. Depends on whether the candidate claims to know Python on their resume. Absolute utter woke bullshit! More leetcode prep time leads to passing leetcode interviews more often. The real solution is having minds without it. A surgeon with many experience at a top hospital most certainly does not get grilled on organic chemistry trivia from their undergrad classes when chaning jobs. You have CI right I assure you I can still discriminate against a candidate both consciously and subconsciously during a live algorithm question now. I think this partially explains the phenomenon of external candidates at Google entering Google at the college-hire tier when they may have been repeatedly promoted at their prior employer. Interviews are another thing entirely. Climbing Stairs. My experience is that people who dedicate lots of time to development outside of work burn out around the senior engineer level because they never get to use the cool techniques they play with on their own time.

Biotech interviews, for example, are usually conversational: what have you worked on before[0], how would you tackle this new problem, or troubleshoot a particular problem. You can certainly get good at it with an internet connection and a hour every day. Is Graph Bipartite? In order for me to add my family to my insurance I had to provide identification for each of them, including a marriage certificate and drivers licenses for myself and my wife. And in some sub-specialites where you are implementing graph algorithms and more, a subset of algorithms is in many ways a relevant interview question. Before leetcode we had microsoft defining the industry interview process with bullshit lateral thinking puzzle questions, and now nobody knows about their existence, nobody complains about them on HN and you never, ever run into them. Prima facie, this seems plausible. Someone who freezes up during an interview may be the coolest head in the company while restoring a database backup during an outage, and vice versa. The key here is "a problem space not seen before". I think that most people here are mistaking the finger for the moon.
