Contractor Interview

Anonymous Employee
Westford, MA

I applied in-person and the process took 2 weeks - interviewed at Juniper Networks.

Interview Details – Background check, interviews. I knew everybody already.

Negotiation Details – A pain in the backside. They down'd the offer in title because they "didn't have the reqs". Which I think is bs: apparently, the way you get promoted is you resigned, work someone else for a year, and then get promoted to "Distinguished Engineer" to come back to Juniper, if you're not already sick of the place.

Very Easy Interview

Senior Program Manager (Contractor) Interview

Anonymous Employee
Remote, OR

I applied through a recruiter and the process took 4+ weeks - interviewed at Juniper Networks.

Interview Details – Through a recruiter, I was contacted by a director-level head of a PMO which was starting up. She was very busy, explained the situation and I was able to depict for her how I had enjoyed successes in past engagements in building & operating PMOs. Since she was in a hurry, she hired me after a 20-minute discussion. Six months later, they laid everyone off and bought out the long-timers because the stock price was depressed from losses caused by poor executive management decisions that incurred excess overhead costs and becoming less competitive by trying to do business in areas they had no expertise.

BTW, all work was performed remotely - which is not an option in this system.

Interview Question – How do you deal with ambiguous situations?   View Answer

Negotiation Details – Negotiated the rate with the intermediary recruiter.
