The average quoted of 38000 Lira is on the high side. I think they're throwing overtime in there.
Last month I got just under 30000 Lira. Then there's a 3 monthly bonus, so average maybe around 34000 lira per month.
On top of that you get Hotel Accommodation in Istanbul, or a 2000 Lira allowance. This allowance was the same 7 years ago, and gave you "reasonable" options for an apartment. However, as the average apartment increases rent 10% each year, the allowance now will get you very little in a crappy area, unless of course you want to dip into your own large salary
Very low when you consider the extremely volatile currency. What you join on may be very very different a year later in your home currency.
