I was asked to give a presentation about myself and my experience.
He asked me to write logic for Switching Light, Fan, AC in a room with some constraints.
Paraphrasing: If you submit a work proposal and it's rejected, how would you handle it?
Firmware and some OS related questions.
All they cared about is where I live, they couldn't understand why someone would want to look for work on Long Island.
OOP concepts and C++ question, 3 benefits passing data by pointer to a function
Talk about c++ the difference among const char* a; const char* const b;
They give you an assignment which has the question like this. Obviously one is allowed to decide what he wants and documents everything or every assumption made. However you are not allowed to ask them questions about the assignment The exercise exists in the implementation of a non-volatile memory storage component. This component should be able to backup and restore values corresponding to a unique attribute identifier. For the simplicity of the exercise the underlying non-volatile memory (eeprom, flash, …) can be modelled as a file. Component Specification • Implement the basic implementation of this component based on following API description: typedef unsigned char UInt8; typedef UInt8 gpNvm_AttrId; typedef UInt8 gpNvm_Result; gpNvm_Result gpNvm_GetAttribute(gpNvm_AttrId attrId, UInt8* pLength, UInt8* pValue); gpNvm_Result gpNvm_SetAttribute(gpNvm_AttrId attrId, UInt8 length, UInt8* pValue); • Make sure the implementation supports different datatypes for pValue. Some examples: o Basic datatypes like UInt8, UInt32,… o An array of UInt8 o Structs like for instance: #define MAX_LENGTH 20 typedef struct { UInt8 id; UInt32 options; UInt8 length; UInt8 data[MAX_LENGTH]; } gpTestData_t; • Ensure the implementation discovers and corrects corruptions in the underlying storage. • Extend your solution with a unit test. • Pay attention to optimize knowledge transfer to other developers
There were questions on data types, state machine and prior work experience.
