Don't believe those 5-star reviews: they were written because of the HR department to improve tanking reviews in the last 3 years. They hide the true situation from outsiders
If you've heard about strategy work - don't believe those words. It's less than 1/4 of projects. Almost all work is about legal/economics.
No work life balance: expect 80-100 hous. More than at MBB. Unrealistic expectation, conflicts, and late night/weekend work.
No culture: the firm's culture pre-PE acquisition vanished. Half of my colleagues disappeared in 2022. Many left by themselves to avoid nasty surprises after layoffs on client's side. Those who stayed - just try to survive. Lot's of conflicts and backstabing. Put work on others. Avoid discussions and responsibility. Everyone would ignore you if you have a question or need advice. Abusive environment due to both managers and leaders. Don't expect a positive regard for doing hard work.
Everyone avoids solving client's problems to avoid responsibility/blame. Leadership just pushes new ideas to sell more project and avoids participation in project meetings. When clients start to ask hard questions, managers just throw juniors under the bus to shift blame and avoid questions during performance reviews. Best strategy - not to say anything and not to attract attention.
If the firm promissed you anything - don't expect that. The promise is worth nothing - the firm will forget about it in 1-2 weeks. And your request will be just ignored even if you remind about it.
Greed is paramount. Layoffs started when growth was 10% instead of 25%. 30+ people were impacted with 2 weeks of severance. You are not an employee. Not a team-member. You are a resourse.
Don't expect to survive for long or learn much. Don't expect to stay. Save your own time and sanity. If you got an offer - decline. Unless you plan to work for a couple of months max. It's not worth it. Their salary is not worth all the troubles.
