Ericsson Software Engineering interview questions

Got a call from a Manager for a phone interview. Round 1: Phone interview with the manager. Scanned and discussed every point mentioned in the resume. Asked basic networking concepts. Round 2: Coding in C (gave an option between arrays and linked lists) plus some OS concepts Round 3: Networking-scenario based questions, mainly on routing algorithms Extended an offer after 3 weeks. Interview process was smooth. HR is pretty cool and cooperative.
