Explain about a situation where you have design something and that went into production?
Adaptive autosar stack and cpp programming
At job fair : familiar with assembly and c/c++ programming, the difference between assembly and c, how to handle errors At phone interview : explain about fyp, problem face during process of coding for fyp, write a program to arrange given random numbers in array in ascending order At face-to-face interview: undergo programming and electronics test for an hour, finish exam, interview enters the room and begin session of introducing yourself, the things you do during internship, explain bout your FYP, interviewer checks your test paper and ask us to explain for all the answers we wrote down, finish explaining on the test papers, interviewer ask us to explain every detail of our FYP from coding to technical and assemble to debugging errors.
Concepts, Tools, Demonstrate knowlege of design practices, coding and technology questions
Your experience about product deveopment
D: Which OS did you use? D: What does it mean the volatile keyword? D: What does this C code do? D: What does this Python snippet do?
Tell me about yourself. Give me an overview of all the projects mentioned in your resume. Explain to any one of them, which technologies you used. What is the data structure you implemented in it? Explain the approach and Code (Just the required functions) on any text editor: Add 1 to a number represented in the linked list and return the updated linked list. I have explained the 2 approaches and also written the functions. Given a set of characters, generate its power set. E.g. for set {a,b,c} : powerset will be: [ {}, {a},{b},{c},{a,b},{b,c},{a,c},{a,b,c} ]. Initially stuck for some strings, but after hint, I covered the logic. One logic was by using recursion. Another logic is the Binary. e.g 0 1 1 means {b,c}. Approach to implement LRU cache Explain All the OOPS concepts. Some Language-based questions like What are the types of constructors in C++ (My preferred language) From OS, what are semaphores, deadlock, and its conditions? Solve the hourglass puzzle.I will suggest going through all these puzzles.
How would you implement malloc()?
C test: 2 set of functions to implement in C within 1.5 hrs. Not very difficult if you are a regular hands-on programmer Interview questions: low level firmware steps to implement data acquisition using 8 channel ADC. How ADC works? How to implement firmware update scheme? How to differentiate valid binary image and malicious one (hint: use signature authentication)? Some irrelevant questions like: how will you implement sudoku in C, logic to implement VI editor How will you recover if a process is crashed while holding a mutex and another process is waiting on it (this is very specific to OS and linux solves this using concept of "robust mutex") what are some of the challenging problems you have solved, explain projects
