I have been working at Home Office full-time
Flexible Working hours. Many Sections will consider compressed hours or working from home opportunities.
Opportunities to take responsibility for large projects and gain valuable expereince that benefits in developing competencies for promotion.
Many units within Immigration have annualised hours working. This gives a percentage of your salary for unsociable hours working.
Entirely dependant on where you are based and job function. Try to speak to someone within the team you intend to join for advice on working hours to make sure it is the right fit for you. Immigration Enforcement can be early starts and working extra hours may be necessary.
I applied online. The process took 6 weeks. I interviewed at Home Office (Croydon, England (UK)) in September 2016.
You need to first fill in a application form. This has five different competency questions on it. You need to answer these based on the tips and hints that the candidate information pack gives you. Each answer is marked and the candidates with the highest marks proceed to the interview.
There isn't much room for team work in the role, which you may want to consider when taking on this role.
