Valeo Junior Embedded Software Engineer interview questions

Hiring process took 4 days, I applied online they called on same day, arranged for a technical exam next week. Hiring Process: - Technical Exam - 70 MCQ - 2 hrs - English Exam - 1 hr 15 mins. - HR Interview - 20 mins - Technical Interview ~ 1 hr Technical Exam is hard, English exam is moderate for a good English speaker, the hardest of all is the technical interview, it's very subjective, if you're lucky enough, you'll fall into the hands of a good person who's understand and helpful enough to see you accepted and fitting. Interviewers are demanding and expecting a lot though, even for a junior position.

I passed the technical and English exam and then I proceeded to the technical interview. The interviewer was kind and helpful and he focused too much on writing programs and to seeing how you think . He didn't care too much about asking question to see your knowledge. The questions were :(NOTE YOU Will write programs on a PAPER not a computer) 1-Given Matrix A(m*n) and Matrix B(n*p) , write a program in c to multiply these two matrices 2-Write a program which calculates the factorial of a number using recursion function . 3- you are given a hex file and he explained how the file is organized from inside , where at the left side there are addresses and in the middle there's the value of data(8 bytes) and at the right there's a checksum (search for the organization on hex file on the internet) and then he told me to write a program which searched for a special address and changes the value of ONE byte of data . Other guys : the interviewer asked them to write a c program to draw a big X or a big V My advice : you must study algorithms very well and train yourself to write hard programs on a PAPER!
