re: Which branch of engineering is best from a jobs standpoint?

Biomedical engineering is a good field too. There is a high demand to shift from human to robotic health care. Easy example would be a nurse who takes blood pressure to an automatic cuff that does it.

Another example would be surgery by robots.

In the same vein, business process re-engineering is in high demand, esp by multinational corporations. Brush up on your familiarity with Simprocess.

Petroleum engineering will be a declining field. With increase demand for efficient and sustainable fuels, it's clear that many first world countries are reducing the use of fossil fuels for energy. That's why I earlier mentioned power engineering.

Petroleum engineers of the 21st century will be the wagon wheel makers of the 19th and 20th centuries.

Informatics (information engineering) is a lucrative field. The starting salary for a search engine analyst is bc 125k and 150k and goes up to about 225k after about 5 yrs experience. Check monster.com for SEO, SEM, and QA/CM positions.

Another tip...learn a foreign language. With the financial crash of a lot of countries, enterprises are doing a robust diversification of their revenue. English is good to know but Chinese and Farsi are right behind.

Being familiar with Bengali is good too.
