It was a one time interview, technical, behavioural and HR, all in one, and it did not take a very long period of time to get a response, if I were to pick an interview to take again, it would be this one, the experience was very nice

-first was the HR -second interview was with an GL and TL about my knowledge in embedded(different questions about programming - C language- -structure, union, enum - describe -working with bits - set/clear/toggle a specific bit in an number -how much memory did you need for a matrix - heap explanation -compiling steps -CRC example -stack,volatile/const) -the last discussion was with the GL and the HR
