2 hours / day of practice for 30 days will give you enough ability to clear Leetcode style questions. Trust me, it will be worth it. At Microsoft, you have plenty of autonomy over your life and work. Even if you don't work very hard, you get to do interesting things and deliver things of value.

At Infosys you might not work very much, but you will spend long hours in the office. You will have little autonomy and your boss will have great power over your life. Your work will be incredibly boring. In short, it is the worst of all worlds: not low-maintenance, not interesting work, and also doesn't pay as well.
