You have misplaced priorities. As a fresher your primary concern should be what technologies you will get to work on (thereby imparting you a firm technical base on which your future career could fly), or how much good quality of tech work you will get in which particular companies (or at least its relative chances).
Talking of Work Life Balance, as to what it is, it is just as the word says, there has to be a balance, meaning that your office work should not disturb your personal life. For example, if your team lead or manager keeps scolding now and then, or keep putting too much pressure to finish work fast, then it may start affecting your peace of mind even after Office hours. As an another example, if you start getting assigned too much work, and you start getting forced to work beyond officer hours (either by direct verbal order, or by implied pressure), then that too will start affecting your personal life adversely. But frankly, these are not the things you are supposed to worry about in the initial 2-3 yrs. Much bigger aspect as a fresher, is the quality of work you get, and the quality of tech stack you get to learn as part of your work. If you enjoy the work, you will not mind some extra work too. But if you don’t like the work and you are forced to work extra, that will become a torture and you may feel like quitting IT industry altogether. So the quality of work is what is most important aspect. And the usual work hours, are 9-6 or 10-7 pm, though it all varies from company to company, and in many service based companies you may have to do night shifts too periodically. Good luck. Prepare well for the Interviews.
