In this episode of Pagal Dada, we are decoding the success story of Ayesha from NIT Mizoram, who secured a dream internship at the global fintech giant—Visa. Getting into Visa isn't just about coding; it's about speed, accuracy, and conquering the infamous CodeSignal test. Ayesha breaks down her entire journey, from the specific coding questions asked to the "Trick" questions in the HR round. If you are from a Tier-2/Tier-3 college or a newer NIT and think top companies are out of reach, WATCH THIS. 🔥 What we covered in this interview: ✅ The "CodeSignal" Hack: Visa’s online test is famous for being tricky. How to score 800+? ✅ Exact Coding Questions: Arrays, Strings, or DP? What actually came in the exam? ✅ Interview Strategy: How she explained her projects to the panel. ✅ NIT Mizoram Reality: How is the coding culture and placement scene in the North East? Ayesha is a pre-final year student at NIT Mizoram. Despite the challenges of a remote campus, her consistency in competitive coding helped her land one of the highest-paying internships in the industry. connect:   / adarsh_dadaa     / adarsh-dukare-pagal-dada   Detailed Study Roadmap (For Visa & CodeSignal) To crack Visa, you need speed. Their CodeSignal test is time-bound and tests implementation skills heavily. Here is what to master: 1. The "CodeSignal" Special (Speed & Implementation) Arrays & Strings: Sliding Window technique (Longest Substring), Two Pointers (Trapping Rain Water), Matrix manipulation (Spiral Matrix). HashMaps: Subarray Sum Equals K, Longest Consecutive Sequence. Linked Lists: Merge K Sorted Lists, Reverse Nodes in k-Group (Visa loves standard LinkedList problems). 2. Trees & Graphs (The Rank Deciders) Trees: Level Order Traversal, Lowest Common Ancestor (LCA), Diameter of Binary Tree. Graphs: Number of Islands (BFS/DFS), Course Schedule (Topological Sort). Heaps: Top K Frequent Elements, Merge K Sorted Lists. 3. Core CS Concepts (Don't Ignore These!) DBMS (Crucial for Fintech): SQL: Write queries for Nth Highest Salary, Joins (Inner vs Left), and Group By. Theory: ACID Properties (Atomicity, Consistency, Isolation, Durability), Indexing (B-Trees), Normalization forms (1NF, 2NF, 3NF). Operating Systems (OS): Multithreading vs Multiprocessing (How payments are processed concurrently). Deadlocks (Banker's Algorithm), Semaphores, and Virtual Memory. Computer Networks: HTTP vs HTTPS (Security protocols are big for Visa). TCP vs UDP, DNS Resolution, OSI Model layers. 4. The "Visa" Edge (Bonus Points) REST APIs: Basic understanding of GET, POST, PUT, DELETE requests. Security Basics: What is Encryption? (Symmetric vs Asymmetric). System Design (Low Level): Design a Parking Lot or Design a Banking System (Basic Class Diagrams) #visa #nitmizoram #internship2026 #PagalDada #Placement #Stipend #AdarshDukare #softwareengineer #engineeringstudent #interviewexperiences #nittrichy
