HCLTech Transformation/Change Management Consultant (Graduate) interview questions

Graduate position - Change Management Consultant. Interview process very simple, telephone interview followed by an assessment centre. Telephone interview pretty standard, just going through CV and was asked questions like why HCL, and why consulting, why this position etc. Assessment centre was a case study given on the spot followed by an interview. The case study was based around a company who had bought an IT implementation from HCL but have not purchased any business consulting, so you have to sell Change Management as a service HCL can offer to the programme director. This involved doing a 5-10 minute presentation and a written exercise (which was an e-mail summarising your presentation to the programme director). You have 30 minutes to prepare for both. There are 3 main areas to cover: What is change management, What services can HCL offer and how can you get good Value from implementing Change Management.
