As already stated the wait time for any building can vary from month to month and year to year. Unless you can find out if the building you speak of is thinking of hiring a bunch of drivers in the next year its difficult for anyone to say exactly what the wait time for you will be until you get hired on. For example they could have just hired a bunch of drivers making the current wait time less than a year, but when you get in they have all the drivers they need and if, god forbid, we had a large economic slowdown that could make that one year wait time an 8 to 10 year wait time when you get your one year in. Its so dependent on factors that nobody really knows at this point that no estimate you hear will be all that accurate. If you want to become a driver get on as part-time in the building and sign every fulltime list you see whether you think you can get it or not. Eventually one of those signatures will earn you a spot as a UPS driver in some sort of capacity.
