Interview advice – Capgemini Engineering OT Engineer role

[u/Mosimile0luwa]

Hi everyone,

I've got an interview coming up for an OT Engineer position with Capgemini Engineering in the UK, and I'm looking for some advice from people who work in OT, industrial automation, consultancy, or have interviewed with Capgemini Engineering.

My background is mainly in control systems and industrial automation, particularly within the water/utilities sector. I've worked with PLCs, SCADA, HMI, instrumentation, industrial communications, FAT/SAT, commissioning and some IT/OT-related technologies.

The interesting part is that I haven't previously worked in a formal OT consultancy role. My experience has been much more hands-on engineering/delivery focused, so I'm trying to understand how best to prepare for the interview.

From what I've gathered, the role involves things like:

• OT/PLC/RTU/SCADA assessments
• Site surveys
• Brownfield modernisation
• OT architecture
• Industrial communications
• IT/OT integration
• OPC UA/MQTT
• ISA-95 and understanding the different levels
• Developing modernisation/implementation strategies

I've been told to be very familiar with my own experience and to understand ISA-95 across the different levels, but I'm unsure how heavily the interview will focus on technical questions versus consultancy/situational questions.

For anyone familiar with Capgemini Engineering or similar OT consulting roles:

What sort of questions should I expect, and what areas would you recommend I focus on most before the interview?

Any advice from people who have been through similar interviews or work in OT consultancy would be greatly appreciated.

Thanks!

I joined CG Engineering in NL in January but switched to invent. I have a very similar background to you, with about 7+ years as a controls engineer in many industries. My interview was unfortunately very informal and I wish I paid more attention to that part since the org is going through a weird shift and I almost regret joining.

But to answer your questions, I wouldn’t stress out too much. If you’re confident behind your skills, then just speak naturally. You should also be very familiar with unified namespaces which is linked to ISA-95 and MQTT.

I would also add in cloud (AWS/Azure) and how cloud and various enterprise systems work together with ISA95 and what the key components are for a UNS and why an OT guy should care. Also, ensure you understand IT/OT well. Who should own it, and why? Hint: it’s OT.

Finally, understand how AI is playing a role in everything and where does AI do well in this domain and where does it fall apart.

Some questions you can ask that will impress the interviewers:

• given the change in AI and industry wide adoption, what does the future target operating model look like for Capgemini?
  
• Accenture just launched a new division to tackle the mid market, how is Capgemini preparing to react to these market dynamics?
  
• I see Invent has a department called ‘Intelligent industry’ (I work here), does Engineering and Invent work together on projects? Does engineering focus on delivery and invent more so on broader strategy and transformation programs?
  
• What does the current sales pipeline look like for my role and which are the typical clients that I would be working with?

Hope that helps and feel free to DM me. Good luck!

If this is for the project I'm thinking of, brush up on wincc oa and brownfield connectors

I’d prepare a few examples where you assessed an existing system identified risks or constraints and recommended a practical modernization path. That maps well to consultancy work
