Pros
Big salary if you're Russian or expat and work in their Montenegro office (salary negotiated net. Company uses local shell companies to avoid taxes). Safe and quiet city (Podgorica, Montenegro). Working hours are generally ok.
Cons
Very low job security due to Russian owners acting randomly and senior management not being competent enough to do their job. People promoted based on favors and 'who knows who', leading to incompetent managers in high positions and low staff morale. Highly immoral field of work (90% of customers lose all their money). High staff turnover. Very low long term career prospects. Zero people management skills (constant hiring and firing). Low long term success prospects for the company due to Forex market being clamped down on. Boring place to live and work (Montenegro. Pretty but small and nothing to do!)
