Jan's description of CSP, ESP and FSP is spot on. Typically Energy Insights analysts would be an ‘expert path’ hire as opposed to a traditional consultant hire. The real difference is that your role in a project will not be that of a generalist consultant but more to contribute in your area of expertise (which will be something related to energy). 

• Prestige is a made up concept - what you really want to know is how being an EI analyst impacts future recruitment outcomes. The answer is that it is not as broad as a generalist but you will get amazing roles in any energy related fields.
• It is likely that you will do most of your work outside of client engagements with a broader McKinsey team, but you may also be staffed on projects depending on the need and your skillset.
• In terms of shifting to the generalist consultant path - it can happen but it is very difficult. You will need Partners to sponsor you and and senior people in the firm to push for you to become an Associate. It is more likely in years where demand for consultants is high and recruitment is not going well.
• Interview processes vary but will most likely include some form of casing, PEI and interviews with regards to your knowledge in the energy field. Make sure you get the full details from HR for the interview process.

Hi there,

The first/short answer is you need to ask them yourself! Pick up the phone and talk to HR and/or talk to people at the firm. Ask these questions on the phone and you'll get a much clearer answer!

Ultimately yes the EI Analyst position is less prestigious and focuses more on research/support (If I'm thinking of the right role). You will not be able to shift to consultant 1-2 years in.

Again, speak to people specifically at that firm+office to better understand where you'd fit in!
