Lengthy, multiple interviews with "Directors", who are sales managers of teams, usually responsible for around 10 people each. All the interviews are fairly similar and not difficult, there is a role play session where a fact sheet is provided. Finally, you will meet with the manager of the managers, known as the "Managing Director". The story is that the firm is so process oriented and thoughtful, that they have a lengthy process to get the right people in the job.
The truth of it seems that the company likes to hire in groups across multiple locations, and send them to training at a central location, and the intakes are set during set specfic times of the year. They do not have these trainings on a rolling basis. Meaning, it probably has more to do with managing the cost of hiring and training. Their sales module is also very lengthy, meaning for a new hire to provide a positive return on the investment made, could take a long time.
Those who started interviewing in June, will get hired in August and be sent to the training in the beginning of September's intake.
The interviews are to simply keep the candidate interested because the company doesn't want to spend money constantly hiring and training each month. They figure this will help them get the most interested people to do the job. Management and HR have very poor communication. Managers do not really know where you are in the interview process. They could be your first interviewer, or your 3rd and they will all ask you if you have interviewed with at the office with anyone before.
Fairly routine questions for someone in the industry and understands the sales processes the firms tend to like. Ironically, turnover is high but not unusual for the industry.
