Okay, it's in Dutch ... but the dossier at Dutch translation-focused magazine Filter, Arnon Grunberg en zijn vertalers, is pretty impressive.
It includes (click on links under table of contents ('Inhoudsopgave')) pieces by translator-into-English Sam Garrett, as well as, for example, Philippe Noble on the French reception of Grunberg's work.
(Lots of Grunberg under review at the complete review, of course: check out, for example, Tirza or Onze oom.)
