Resident Engineer Interview

Resident Engineer

I applied through other source and the process took 2+ weeks - interviewed at Sonus Networks in August 2010.

Interview Details – You will be tested on unix -since all the platforms are solaris base, so be sure to know at least basic unix. Sip -is the protocol of choice, so ensure that you are familiar with all the messages and conversion to other protocols -eg sip to ss7. Networking 101 is also a must. General telephony routing knowledge is also helpful.

Interview Question – The most difficult question one about oracle database queries. I had not used oracle up to this point.   Answer Question

Business Development Interview

Business Development
Westford, MA

I applied through an employee referral and the process took 4+ weeks - interviewed at Sonus Networks in August 2010.

Interview Details – Employee friend of mine referred me to Strategy group. I had previously worked at Sonus so I knew a number of people within the company, although I did not know the hiring manager. Had initial, quick phone conversation with VP Strategy and he suggested I come in to meet him in Westford. Met with VP Strategy and had a very informal discussion around the industry, the emerging technologies and the competitors within the space. Discussion lasted about 1.5hours.
Met with VP Human Resources and we discussed overall processes Sonus operates under, pay plans and structure around packages as well as company advancement and mobility options.
After meeting with VP HR, went back to meet up with VP Strategy and he signaled his intention that he was interested in putting an offer together.
Over following couple of weeks, had numerous phone conversations with VP Strategy and negotiations began for an offer.

Interview Question – Since the interview process was very informal and discussion like, there wasn't any one question that was unexpected. The difficulty was in knowing whether the topics of conversation were adequately answered by me.   Answer Question

Negotiation Details – The negotiation phase had a lot of bureaucracy. I sometimes felt like I was negotiating to come work for a 5 billon dollar company instead of a 300 million dollar one. But my understanding is process is far better since 2012. My negotiation was in 2010 where the processes were from prior CEO/CFO
