Your horoscope has Mercury, Venus and Jupiter retrograde making them inherently weak to give positive results especially in banking. Also you are under last phase of Mercury Mahadasha in Mer-Sat from 13/6/2015 till 20/02/2018. Mercury and Saturn are both in 12th house of loss in Chalit + both planets don’t have good combinations for career in nakshatra or sublord. But if you go abroad Mer and Saturn will turn beneficial for you (LUCK will favor you).
Ketu mahadasha starting in 20/2/2018 till 20/2/2025 is better for career as Ketu is placed in 7th house in Chalit + has 6, 10 combination in nakshatra and planet.
Venus mahadasha starting in 2025 will change life as Venus is 11th lord and friend of Mercury.Try for a job abroad as it will change life for better.
