```\nStatus: Software Engineer (2 YOE) at a leading semiconductor and wireless MNC\nPosition: Software Engineer at Cisco Chennai\nLocation: Virtual\nDate: May, 2021\n```\nI was hesitant in giving interviews I always withheld myself claiming more preparation the better however I just applied for an open position and this was more of a mock interview for me and I definitely learnt a lot after failing at this one.\n\nThere were a total of 3 continuous virtual interviews held through their platform Webex.\nThe interviews were taken by Senior and Staff Engineers from Cisco Canada (Ottawa).\n\n**First Round (With a panel of 2, some senior level engineers):**\nInquiries about my background,lots of questions on the current role in my organization. the Why Cisco and Why this position. 2 questions based on ```C```.\n1. Find error in the C program (it was some char pointer to string and its manipulation. Honestly, I hate pointers! I probably fumbled a lot on this one. I need more practice on it) \n2. How to find whether the platform is little endian or big endian\n3. Count number of set bits (everyhing was good until I changed my bit manipulation solution and ended up using XOR ```^``` instead of AND ```&``` and that was end of it  \uD83E\uDD26)\n3. Some question on Computer Networks (I clarified that had taken up courses in my undergrad and postgrad but have been out of touch).\n\n**Second Round(With a panel of 2, some more senior level engineers):**\n\nWhat is my role in the organization and business unit?\nQuestions on my personal projects mentioned in resume.\nSome C and Coding Questions.\n1. Set memory location to value - for example set ```100``` at address ```0x123456```\n2. Given a string "this is a test" reverse and return "test is a this". (Ended up using C++ after inquiring if that was OK to use. I was given a go ahead but I guess they were looking for implementation in C anyhow ended up solving it pretty easily).\n3. Given an integer ```N``` find all quadruples satisfying ```a^2+b^2 = c^2+d^2``` (where a,b,c,d can be anything from 1 to N).\n\n**Third Round(With a panel of 2, Director and Senior Manager)**\n\nLenghty discussion on my background ,skills, my current work, why Cisco.\nSome questions from director about the biggest challenge I have faced in my current position so far.\nConstraints in the embedded world of software engineering.\n\nAgain a brief discussion about my personal projects mentioned in resume.\n1 Coding question (even though this was way too simple but I overcomplicated it, enough excuses.)\nQuestion : Inspired from my current work scnerios (as I had experience in embedded software engineering) consider a constant array in read only memory ```const int l[] = { 1, 2, 1, 2, 3, 2};``` write a function from scratch to print out all the elements that occur odd number of times i.e output : ```2, 2, 3, 2```\nThere was a constraint on memory (you could not create a copy of array, manipulate it in anyway using stack memory since it is limited for this scenario). Again to be solved in C. (Messed up few C basics of passing array to a function etc.)\n\nToiled for a bit arrived at ```O(N^2)``` solution. Almost running out of time and was given a follow up question where the output all numbers with odd frequency needed to be printed only once i.e output : ```2, 3``` for given test case.\n\nResult: **Rejeced**.
