I applied online. I interviewed at Ericsson (Bengaluru) in Jan 2013
Interview
Interview was held at the Bangalore Center and it was conducted in 2 phase. Each phase comprised of 4-5 pure technical rounds. The focused areas were as follows:
1. General automation questions
2. Networking and Protocols.
3. Wireless technologies.
4. Troubleshooting telecom issues
Interview questions [1]
Question 1
Mostly on programming concepts, data structures, algorithms, networking, wireless
I applied through a recruiter. The process took 1 day. I interviewed at Ericsson (Athlone) in Feb 2013
Interview
The final interview was a face to face interview with four people: two line managers, one HR representative and a lead architect.
1 - Technical background and reasoning: talked a lot about previous experiences and possible solutions to past problems. Every time that a specific past problem could be used for an existing Ericsson problem analogy, it was made so. There was quite a lot of talk about changing previous solutions that I was describing to try and gauge my adaptability and reasoning on dealing with new (and applicable to Ericsson at that point in time).
Quite a lot of whiteboard drawings involved in this part of the interview.
2 - Personal adaptability: there was some questions in regards to how I was planning to adapt, as at the time I would be moving countries (and continents) if I got the job. Not invasive questions, but well grounded ones that made sense both for setting my expectations and from the interviewers assurance as well.
Interview questions [1]
Question 1
To change an existing solution that I was describing at the time to be able to be updated with no downtime at all. Explain the required changes on the architecture to support this and the trade offs.
As the current solution did not require any hard no-downtime requirements (i.e it was only released on weekends where there was no active users) there was quite a lot of changes involved in this and it took quite a lot of time.

Interview
mostly questions regarding my previous job role which involved telecom stacks, protocols, SS7 etc. programming questions in C, C++ and shell. some algorithm questions. read sorting and searching algorithms and complexity of algorithms

Question 1
improve the complexity of a certain algorithm in real time
