friendly people in interview, but it did not take me long to realize that I was not qualified for the position I applied for. I did not want to leave so I suffered through it.

Resume-Based Questions Projects: The interviewer asked detailed questions about the projects mentioned on my resume. They were particularly interested in the technical stacks I used, including any specific libraries or frameworks, challenges I faced, and how I solved them. They focused on my experience with the MERN stack and Flutter, especially in any recent projects involving third-party integrations, such as payment gateways. Role in Team Projects: Since I had experience as a Team Lead, they inquired about my role in team-based projects, how I managed tasks, and any leadership challenges I encountered. They wanted to understand my collaboration skills and how I ensured the success of the project. Quantified Impacts and Improvements: They questioned specific quantifiable results I listed on my resume, like the improvement in user retention and performance improvements in the apps I developed. 2. Data Structures and Algorithms Questions Array Manipulation Problem: I was given a problem related to manipulating arrays with duplicate values and was asked to solve it efficiently. I discussed both brute-force and optimized approaches, using sorting and hash maps to reduce time complexity. Graph Traversal: They asked about graph traversal algorithms, specifically DFS and BFS. I was asked to provide code for both and explain the use cases where each algorithm is preferred. Two-Pointer Technique: Since they noticed my preference for the two-pointer approach, I was given a problem that required this technique. They were interested in understanding my thought process in setting up pointers and handling edge cases. 3. Computer Networks Questions TCP vs. UDP: I was asked to explain the differences between TCP and UDP, focusing on their use cases. I also discussed how TCP ensures reliable transmission and where UDP is more suitable due to its lower latency. OSI Model Layers: They asked for a breakdown of the OSI model layers and for me to describe how each layer interacts with the others. They specifically focused on the transport and network layers. IP Addressing and Subnetting: The interviewer asked questions about IP addressing, including the difference between IPv4 and IPv6. I was also asked to explain subnetting and calculate subnet masks for given IP addresses. DNS and HTTP Protocols: They wanted to understand my knowledge of the DNS protocol and how the HTTP protocol operates over the internet. I was asked to describe the HTTP request-response cycle and some HTTP status codes.
