Pros
1. Good pay (but not good enough). 2. They do promote people very quickly (but then you don't get paid more so people just leave with their new promotions). So you can get training then get out. 3. You can (and probably will) live in different parts of the country, so if that appeals to you it could be a plus.
Cons
I'm not bitter and everything worked out in the end, but there were a lot of factors that have made Tata an undesirable employer. 1. Talking with other people from across the country that were trained at the same time as I was, Tata recruiters lie to get you in the door. They claim that they are so big and have clients all across the country so they will definitely be able to place you where you want to live and you will be able to stay there. So people from California they told would be able to stay in California, or if you wanted to be in New York, etc. I was skeptical about it but figured the pay was good enough that i'd test it for a year. It was about a 50/50 on if you were given the location they were promised. Tough break if you were planning to be near family or spouses. 2. They try to push everyone into less technical roles and then they try to reduce your salary if you are a technical role. 3. It doesn't seem like they have enough work for the people they hire. Many people weren't even given projects to actually work on before they left (people went months without being given anything to do), while others were assigned jobs to then have those run out and then they were left with nothing to do. While this isn't the worst thing in the world, it's a pretty bad career move to be in the industry too long with no experience to speak of. I believe this stems from the fact that they are trying to increase the number of hires in the United States but do not have more work to accommodate that. Also a root cause for problem 2 I believe. 4. As stated in the pros section: they will promote people but then they won't pay you more so people always just leave to get a better paying job with their new position. This, coupled with the other reasons, leads to very few people staying with the company. 5. Their email system is terrible. TERRIBLE. Even though it sounds like a minor thing, it is so bad it is worth mentioning. There is no search functionality. If you want to find an email from last month you start scrolling. Furthermore, it takes about a full minute from the time you click an email to when it actually loads, and sometimes longer (on any computer, i'm not kidding!). With how bad it is, people dread opening their email so people respond much slower. We were once told that you need to have the subject line of the email be descriptive enough or people won't open your email...
