Pros
There is concern taken by senior staff to limit working hours, which at times can be extremely brutal. It is unlike other consultancy firms in this regard. Some senior staff take a genuine interest in junior stuff, which helps you into feeling welcome.
Cons
Although pay has been increased slightly, it is still significantly below competitors operating in the same vertical. The lower salary is justified by the "great culture" at CIL, this culture has been somewhat eroded in recent years, this is in part due to a fairly high staff turnover, and a rather aggressive growth strategy. There is almost a constant stream of feedback (if you are on a project for a week or more, meaning it is not uncommon to receive more than 3 pieces of formally written feedback a month). Since significant importance is attached to these pieces of written feedback during your 6-month review, junior staff can be fearful of making any mistake, which are often written up in your feedback. Feedback is often contradictory and I have experienced and witnessed a blame culture, where more senior staff use the written feedback to frequently deflect responsibility downwards for bad output. This makes feedback very unhelpful for personal development. CIL has a good product which is respected by industry, this means that project managers often give the project team little freedom to deviate from established methods and templates. This rinse and repeat attitude means that whilst the sound of Strategy work for a Management Consultancy may sound appealing, the reality of it is that 90% of work is tedious and monotonous.
