Screened applicants are invited to take one or two rounds of an online programming test (OA), which focuses on programming skills and problem-solving abilities as an initial measure of the candidate's technical level. In some cases, the OA is followed by an initial screening call to assess culture fit and communication skills.<\/p><p data-sourcepos=\"5:1-5:117\">Successful OA candidates will move on to one or two rounds of phone interviews. These interviews focus on evaluating the candidate's coding and problem-solving skills by solving technical problems in real time, while also discussing past project experience to determine if the candidate is a good fit for the position and compatible with the Meta culture. Performing well on the phone interviews is key to advancing to the next stage.<\/p><p data-sourcepos=\"7:1-7:173\">Finally, there are Onsite Rounds, which typically consist of four rounds of interviews, each lasting about 45 minutes, to thoroughly assess a candidate's technical and interpersonal skills. This typically consists of two coding rounds, one system design round, and one behavioral round. The coding and system design interviews ask complex algorithmic and design questions to examine problem solving and system scalability, while the behavioral interview focuses on assessing cultural fit. The entire interview process is difficult and pays close attention to the applicant's overall ability.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div

distribution of types of programming questions. Analysis of LeetCode data shows a strong focus on depth-first search (DFS), breadth-first search (BFS), and double pointers, highlighting Meta's preference for topics that deal with complex tree and graph traversals and efficient array manipulation. Surprisingly, Meta has relatively few Dynamic Programming questions compared to other companies, which are often common in tech company interviews. This difference suggests that Meta is more specifically focused on ensuring that candidates are proficient and effective in working with data structures in real-world scenarios.<\/p><p data-sourcepos=\"3:1-3:184\">\n<table id=\"tablepress-5\" class=\"tablepress tablepress-id-5\">\n<thead>\n<tr class=\"row-1\">\n\t<th class=\"column-1\">Features<\/th><th class=\"column-2\">Percentage<\/th>\n<\/tr>\n<\/thead>\n<tbody class=\"row-striping row-hover\">\n<tr class=\"row-2\">\n\t<td class=\"column-1\">Misc<\/td><td class=\"column-2\">12.3%<\/td>\n<\/tr>\n<tr class=\"row-3\">\n\t<td class=\"column-1\">Simulation<\/td><td class=\"column-2\">1.5%<\/td>\n<\/tr>\n<tr class=\"row-4\">\n\t<td class=\"column-1\">Two Pointers<\/td><td class=\"column-2\">15.4%<\/td>\n<\/tr>\n<tr class=\"row-5\">\n\t<td class=\"column-1\">Adv.

There's a rule here: the contribution of each integer to the final sum is not equal, but is multiplied by the 'depth' of the integer. For example, the outermost integers have a depth of 1; if you drill down one more layer, the depth of the integers there becomes 2, and so on, with larger depth values the further in you go. Our task is to figure out the sum of all those integers, and each integer has to be 'weighted' according to the depth at which it lies.<\/p><h5><strong>Problem Solving Ideas:<\/strong><\/h5><p data-sourcepos=\"9:1-9:92\">Doesn't this question sound a bit like playing a treasure hunt?

It's like if you add another legal fence around the outside of a legal house, the whole structure is still legal.<\/p><\/li><\/ul><p data-sourcepos=\"24:1-24:37\">These three rules together define the validity of \"bracket matching\". It covers all possible \"legal\" combinations:<\/p><ul data-sourcepos=\"25:1-28:0\"><li data-sourcepos=\"25:1-25:10\">No content (empty).<\/li><li data-sourcepos=\"26:1-26:11\">Parallel arrangement (splicing).<\/li><li data-sourcepos=\"27:1-28:0\">Layers are nested (closed).<\/li><\/ul><p data-sourcepos=\"29:1-29:113\">With these few simple rules, we can determine that strings like ([]), ()[[()]] are correct, and strings like ([)], (() are incorrect. This has a wide range of applications in areas such as compiler design, data structures (the application of stacks to check for bracket matching), and so on.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-600aced7 e-flex e-con-boxed e-con e-parent\" data-id=\"600aced7\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-25cd5077 e-con-full e-flex e-con e-child\" data-id=\"25cd5077\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-497e1ab7 elementor-widget elementor-widget-heading\" data-id=\"497e1ab7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Interviews in North America<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-4162386e e-con-full e-flex e-con e-child\" data-id=\"4162386e\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-163c89db elementor-widget elementor-widget-heading\" data-id=\"163c89db\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<p class=\"elementor-heading-title elementor-size-default\"><a href=\"https:\/\/csoasupport.com\/en\/amazon-interview\/\">1.
