Jet and Air India will be showing openings again quite soon, now what matters is how well we are prepared for the written, one cannot expect to land up to a fair job without completely in command of the written test requirements, We cannot just rely on one option so it is always good to find or try to make a way out that can lead closer to what you want. Also, strong determination is required towards what you want, same goes with going to Botswana, a good ground work, knowledge about most of the things before handed and then giving it a best try is the best approach. Other than that start saving money, u never know when you might need it and study well.
