This used to be fairly popular (both ways), but as more lawyers realise that life is not that rosy on the other side, we find it less common.
If you are about 2 years PQE (post-qualification experience) or above, in a field of law related to in house work – employment, company commercial, conveyancing, property, M&A – it is not too difficult in some areas. However you need to think carefully as to the reasons for the move.
Salaries in house can be very low, although the working conditions often make up for it. NQ (Newly qualified) moves tend to be harder as in house departments prefer experience before considering candidates. Often there is no-one in the organisation to provide training. Quite a lot of posts are offered on a contract basis, and life can be a little uncertain in multi-national companies.
