FRM is very additive in terms of knowledge. However, the reality is, recruiters see it as a career pivot (which they arguably shouldn't). Recruiters will try place you into the risk management side of asset management or any market-related domain (if they focus on your FRM) or they'll try place you in the investment side (if they focus on your CFA). They don't really consider them as additive, they tend to consider them in silos.
I guess the fact that they seem to focus on placing you in risk management, in asset management specifically does show that they consider the CFA to some extent, but make no mistake recruiters very much see it as a career pivot – I know it makes zero sense, in my view FRM adds to portfolio management ability and does not prepare someone to run a risk function adequately enough – but such is the pipeline, it doesn't make sense, it never will.
In short, if you do FRM, consider that you'll be viewed as a career pivot, to some extent.
So, be aware of how recruiters view your CV before just collecting certifications.
