Paint designed for uneven surfaces may be sold under a range of names including elastomeric paint, high-build paint, crack-free paint or renovation paint (which is basically a filler and undercoat in one). These paints are much thicker than ordinary paints which gives them much better coverage.
A plain flat finish paint (in a scrubbable formulation) is what I've found that best conceals these flaws. The light bounce back in minimizes and the wonky, uneven texture to them are not nearly as noticeable as before.
Flat paint, with its velvety, matte appearance, is the best choice for hiding any wall imperfections due to its lack of shine and reflective properties.
Traditionally, an uneven wall can be corrected by either plastering the wall or, if the wall is particularly irregular, installing plaster boards. Both of these methods will require the skills of an expert, especially if you want a guaranteed professional finish. An alternative method is to install PVC wall panels.

Smooth Finish: No one wants bumpy, patchy walls. PVA drywall primer smooths out inconsistencies in texture, making the final result look silky smooth.
Sanding is probably the easiest way to do it. You could skim coat the walls but that'll take forever and isn't exactly easy. You could also use spackle or joint compound to skim over the imperfections then sand to blend it into the walls. They won't be perfectly flat but the imperfections won't be as noticeable.

Avoid using eggshell paint in high-contact, high-traffic areas such as door and window trim, baseboards, cabinetry, and doors. It's best to use semi-gloss paint in these areas.
Flat and eggshell paint can help you hide imperfections but may be problematic if you expect the painted area to get dirty. On the other hand, glossy paint is much easier to clean, but doesn't do a good job of hiding imperfections.
