Training, work culture, exposure to real work.
The work allocation was a bit hit and miss in terms of getting access to a variety of work in the short time we were interning.
Advice to Potential Interns
L.E.K. has a true work hard, play hard culture so if you enjoy that, then L.E.K. is a place you will thrive. The majority of engagements at L.E.K. are very strategy or due dilligence oriented, with performance improvement being just a small part of what the firm does (but that is definitely changing). L.E.K. historically takes on many shorter term engagements of 3-6 weeks so you're likely to be on quite a few different cases in your first year.
At junior levels, the work tends to be quite research-oriented, with Associates generally being responsible for conducting market research, phone interviewing and gathering data. Client interaction at Associate level tends to be minimal although client secondments come up from time to time. The majority of the work will be office-based which is a bonus for those who prefer not to travel everyday.
Some of the highlights of L.E.K. include its structured training curriculum, the availability of international "swaps" (working in another L.E.K. office abroad for six months) and its sponsoring of top-tier MBA programs. The promise of a fully paid MBA at the likes of Harvard is probably one of the biggest drawcards to the firm that allows potential candidates to easily look past its relatively low profile brand.
Socially, the firm holds a number of social functions throughout the year and the teams tend to be very cohesive, a byproduct of working mostly from the office rather than from client sites.
As is common in Consulting, you can expect to work long but not meaningless hours. L.E.K. emphasises not letting your work leak into your personal life and thus discourages you from working after hours from home or on weekends.
I would say the kind of exposure and training you receive will be almost on par with what you would see at a McKinsey, Bain or BCG albeit with shorter engagements and often smaller clients.
All in all, I'd recommend L.E.K. as a great place to launch your career.
