Whether it's reversing a string, an array, or a linked list, the underlying concept is the same. Once the core principle is understood, it can be applied across various data structures. ✅ I was asked this specific problem during a coding round with a MAANG company, where the task was to reverse only the letters in a string, skipping any punctuation marks or symbols. While the concept seems straightforward, it provides a great opportunity to strengthen the basics such as character handling and string manipulation. I think practicing problems like this makes it easier to tackle more complex string-related questions when you're preparing for technical interviews. 🤓 Feel free to check out my solution with detailed steps and comments in the link below! 👩💻 #embeddedprogrammer #codinginterviews #MAANG #day4of7

When recruiting for roles within Software Engineering it can be hard to find the necessary skills due to their availability... however, there are a few programming languages that make that search even harder 👀 Go, C & R can be the bane of your life when they are a requirement 🥵 I'd always recommend to Go Engineers that they put "Golang" in their CV over Go as it's an easily searchable phrase via a boolean. When it comes to C & R - I don't have a clue how you can make yourself more visible on searches when it comes to recruiters finding your CV. So until I find that solution, the below will be my reaction to seeing a C & R requirement come through the inbox 🤣 Any tips? #recruitment #C #R #software #Go #Golang

📍Computer Network Interview Questions 🚀 When it comes to cracking Software Development Engineer (SDE) interviews, mastering the core subjects is crucial.

To help you prepare, here are some essential Computer Networks questions you should know. 📌 Save it 👍 like and 📲 share with your friends and connections & follow Vaibhav Mishra for more such contents 🧑💻 #computer #network #interview #questions #software #development #coding #practice

I have a memorable story related to this problem...... In my life, my first technical interview was at Chaldal Engineering Ltd. During my first technical interview at Chaldal Engineering Ltd, the interviewer asked me to find the longest consecutive subsequence in an unsorted array. The task was to identify the longest subsequence that, when sorted, has consecutive elements with a difference of 1. My initial solution had a time complexity of O(n log n), but the interviewer asked me to optimize it to O(n). I couldn’t solve it in O(n) at that time, but today, I’ve managed to solve it with a solution that beats 100% in time complexity and 99% in space complexity. Interviews truly offer valuable learning experiences! :3 The problem was not exactly the same but was of a similar type. #OctoberChallange #Streak28 #Leetcode daily [28th Oct'24] - 2501.

Calling all system design enthusiasts for a quick discussion! 👋 The system design interview immerses you in architecture and scalability, but with just 45 minutes, how deep should you dive? Here's the question: In a system design interview, would you prefer to: Deep dive into a specific component: Focus on the intricate details of one element (e.g., recommendation engine), showcasing your in-depth technical knowledge. Provide a high-level overview of the entire system: Outline the core components and their interactions, demonstrating your understanding of the big picture and scalability. There's no single right answer! Both approaches have their merits. Let's discuss in the comments:✏ What are the pros and cons of each approach?📥 When might one approach be more effective than the other?📥 How do you decide which approach to take during an interview?📥 Have you ever had to make this choice during a system design interview? Share your experience and how you navigated. My book "Ace the System Design Interview" will be releasing soon 📔📕 Follow me for the release date: Naveen chandrawanshi ✅ #systemdesign #interviewprep #coding #softwareengineer #softwareengineering #faang #dsa #java

Bugs can get you rejected in coding interviews💔 Here are tips to avoid those bugs and debug if they do pop up: ✅ For avoiding bugs, understand the problem statement first and make sure you: 🔶 Plan before you code: Outline your approach and algorithm to reduce chances getting bugs. 🔶 Test in Stages: Don’t test the entire code at once but instead, test small parts of as you write. ✅ When it comes to debugging, you can use IDE debugger or follow these steps: 🔶 Isolate the Issue: Identify which part of the code has a bug and isolate it for better debugging. 🔶 Review Logic and Syntax: Check the code line by for any logical/syntax error or inconsistencies. The best practice is to participate in several mock interviews before the actual one. You can connect with me or other MAANG mentors through Preplaced.

Want to prepare for your next FAANG Interview? Here I will walkthrough a solution for Leetcode 449: Serialize and Deserialize a BST. Why Serialize a BST? Serialization is converting a data structure into bits the purposes of storing the data in memory or as a file for later retrieval, or to use less space when transmitting it across a network connection. A Binary Search Tree (BST) is usually serialized into a string, which is what we will do in this case. #Serialization An effective method for serializing a BST is to perform a preorder traversal (root, left, right), storing the values in a string separated by spaces. We first start by importing a few libraries that will help us: include <string> include <sstream> include <queue> Then we'll define a function to start encoding a tree into a single string: string serialize(TreeNode* root) { stringstream ss; serializeHelper(root, ss); return ss.str(); } Here we use recursion to take care of the task, by passing in the root (or beginning) of our tree, and then defining a function serializeHelper which will: - store the value held in the node - call itself on the left child of the node - call itself on the right child of the node This eventually processes the entire tree. With this in mind, serializeHelper should look like the following: void serializeHelper(TreeNode* node, stringstream& ss) { if (!node) return; // This is ss << node->val << " "; serializeHelper(node->left, ss); serializeHelper(node->right, ss); } We add the line if (!node) return; for when we get to the leaf nodes and there are no children. In the next post I'll go over the steps to create the deserializer. Thanks for reading! #FAANG #Interviewprep #LeetCode #Cpp

I joined a valuable online workshop on "Building an Engineering Resume". It was a very interactive and engaging session by Saad Aslam and Tech Minds. The presenter shared valuable tips on how to showcase our technical achievements( projects ), skills and experience in a resume. Here are some of the key giveaways I learned from the webinar : 🚀 Projects: This section should have a 'Project Title' and a 'Description' for the project details, including some statistics about it. 💫 Skill: Make two sections of the skills, Technical skills and Soft skills ( skills like teamwork, problem solving, communication). For a student or fresh graduate we should only add the skills we possess, because interviewer asks questions related to the skills we mention in our resume. A better way to showcase our skills is like this "Java (expert), python (intermediate), Git (proficient)" . This way the interviewer can get an idea of the level of questions to be asked from the mentioned fields. 🌟 Experience: mention the position on which you work, company name and the duration of job along with your contributions to the company. ✨ Achievements: Awards / recognition to be mentioned along with any certificates. 💫 Education: This section includes the Degree | Institute from where it is achieved,| city, state,| graduation year and GPA (if required) . Relevant coursework should be mentioned. (Optional ) Relevant electives .
