This company preaches client love, but I did not see any of that during my tenure at Slalom. The things that leadership would say behind the clients' back disgusted me. Of course they need your help and your expertise - that's why you're there! It's inappropriate to make comments such as "their mindset is still in the stone ages" or "they have no idea what they're talking about". It's our responsibility to help them improve and elevate their current processes. I worked at my previous consulting firm for over 7 years and I had never encountered such vile leadership with such a superiority complex.
In terms of career, I was never placed in the role which I was promised during the interview process. They will say they try their best to place people in the right roles but don't be fooled. Slalom has a tough time competing with the Big 4; therefore, they've made their mark in a small number of the same roles.
Also, don't expect to have work-life balance. I live in the city and commuted 3.5 hours a day to Deerfield for months on end without a WFH option. I spoke with my people manager about this, but she was too passive and didn't want to make waves, hence I was stuck without options.
