I got call from recruiter about my application for the WiFi software engineer position. The phone interview was scheduled for the following week. There were two engineers that I talked to. They asked me questions mostly from my resume and some other on computer networks (TCP/IP, 802.11 standards, Ethernet frame header fields, how ping works and how to debug if it does not) and some on embedded software specifically in C. (Little-endien vs Big endien, how to determine which).
