Human Factors
On approach to 16L [Company X] on 16R appeared to overshoot the LOC (Localizer) twice the second time causing the Resolution Advisory. We responded immediately and re-acquired the [Company X] jet (it appeared to very nearly end up underneath us). The auto pilot was off and we were in VMC. After we were clear of the conflict; I descended and reacquired the glide slope and flew a stabilized approach to the runway.
A320 First Officer reported an NMAC with another aircraft on approach to land.
