Tehcnical intetview through a portal in real-time: - implemet strcpy(); trick what if buffers overlap (copy backwards) - implement debounce of an interrupt At home: read a data file with 12-bit packed data (format not specifed) and produce a report of the last 32 entries and largest 32 values in the list. Spent an hour on it (including the time to spin up a linux VM development environment Note: based on the CRLF in the test data they are a Microsoft shop. Basic information was missing, like the format of the input data. Got my wrists slapped for being "incomplete", so did dilligence to get all aspects "perfect" to specification and resubmitted (4 hours of analysis, QA and code polishing).

A long binary bit string is stored in a char array (size 128), write a function, given the char array and a number N, return a char array that has the original binary bits shifted by N bits.
Write the memcpy code. What if the processor is 32 bytes and want to transfer 4 bytes at a time? What will happen if no. of bytes are odd number? How to code it? I am not good in writing code if someone is looking at it and also time is running. So I didn't do well.
