Pros
HR will consider you for all their learning and development plans
Cons
HR is just an HR and does not have the right to value your career or support your progress in your reviews, designations and salaries. I had a bad experience with BDO as they tagged themselves under 'For People', but they should change it to 'For Partners' or 'For Directors.' Read the JD before you accept the contract and make sure whatever is in JD is the critical responsibility. If your manager changes the JD exactly after joining and doesn't communicate your objectives properly, complaint immediately instead of waiting for a day when he/she will call you to say, today, this hour, or this 5 minutes are your last five minutes in the company, well HR will be there just to witness as they have no role or control to do anything because they will say, it's none of my business. Of course, not directly, as I heard from HR that it's only him that can take a decision because he brings business, and that's his final decision; sorry! It's hard to be part of my job, but we will provide you with references for future jobs whenever require and wish you the best.
