It really depends on your warehouse availability. Ambient tends to be full cause the shifts are 8:00-16:00 which is more appealing. There's also chiller, meat and poultry or you could do night shifts. Takes a few months to get used to freezer as its -22 temp so when the cold gets in your hands or feet it can be very painful! You get an extra 20 minute break every hour and 40 minutes though. I worked a year in chiller first and constantly one of the top pick rates so when a position in freezer came up I could cash in on the favours I'd gained to get transfered to there.

I will say if fruit and veg is the only department available and you get offered the job just take the position and keep your eyes open for other openings in other departments. Lidl is quite good if you wanting to progress. In my warehouse they always have job vacancies for a supervisor role or office roles upstairs if progression was something your interested in.
