Interview Preparation Tips

Interview preparation tips for other job seekers - Round 1: A video conference over Zoom with a panel of three based in Canada
Round 2: Face to face if the panelists are in India
A written test on the same day.
Round 3: HR


Ciena had a team of writers in Canada, but they reduced the team there and are now recruiting in India. The company is a good workplace, but doc management isn't. The Director sounded a bit cold. The lady was warm, and another manager acted too smart.

From some writers who worked there, the feedback isn't great. There is no proper doc workflow. To collect information, you must go to the engineer's desk or call him/her. No wiki or specs docs. No proper doc publication system either. You update the doc based on the input received from the management. The doc is just a support team here. No proper tools: some use FM, some docs are in Word and Powerpoint, and some in HTML. Hard set deadlines, but it's difficult to get reviews from engineers.

You are asked to come to the office every day. No work-from-home. If you WFH, the day is marked as a leave of absence from management. The company provides free cab service and lunch. Timings are from 8 AM to 5 PM.

Interview Preparation Tips

Interview preparation tips for other job seekers - My 1st round was done telephonic.I was Asked about my L2-L3 testing experience and knowledge.
Interviewer asked me questions about basic and advanced OSPF , BGP concepts.once interview was done interviewer told me that i will be called for face2face interview.But after 4 days, after many followups finally HR told me that my feedback is not positive.When i asked for the reason ,they told me that my bgp concept is good and other concept like ospf is not good,which is verry surprising as BGP is far complex protocol than ospf and i was good in bgp and bad at ospf.I think in ciena many politics is played to select a candidate.since there is high referal amount paid by ciena,so there is lots of internal politics in hiring.you can only clear interview in ciena if u have good relation with someone important in cciena.
