I would start with understanding where your experience fits best in consulting. If we take the BIG3 companies as an example, there may be multiple options:
- You have some general experience that is relevant for consulting but do not have a deep functional expertise (e.g. 4-5 years as a brand manager). In this case, you should apply for a general consulting trek.
- You have a very deep industry expertise (e.g. risk in banking). In this case, you may be a good fit for an Expert career trek within the research department.
- You have a functional knowledge (very often supplied with the relevant PHD) that suits one of the dedicated operational groups within the company (e.g. operations, implementation, private equity)
- You have functional knowledge in digital that is in line with the newly created subsidiaries (E.g. Digital Ventures or Quantum Black at McKinsey)
Tier 2 and Tier 3 consulting may have even more (or less) options, especially if your industry experience is in tech.
There may be multiple options to approach this:
- Actively monitoring opened roles that might suit your experience on the web-sites
- Sending the resume to HR asking for an advice. If your profile is interesting they might schedule a meeting with a manager or partner from a relevant industry / function or someone who is responsible for experienced hires
- Calling the local offices asking for Information about any upcoming events for experienced hires
- Leveraging your network / linkedin connections looking for an advice on where your profile suits best
