feat(sbb): interview invitation 2026-09-09, write interview brief

SBB Data Engineer (Job ID 103755): invited 2026-08-28 for Wednesday
9 September 2026, 08:30, 45 min on Teams.

Per the posting's own process this is stage 2 of 4 - "Virtuelles
Kennenlernen mit HR und Fuehrungskraft" - so HR together with Andri
Wienandts, not a pure HR screen. 45 minutes shared between two people,
which is the practical constraint the brief is built around.

Two facts worth recording:
- This is the FIRST conversion of the evidence-first cohort (6
  applications, 2 rejections), and it came from a COLD submit. The
  channel plan called for phoning Wienandts before applying; that never
  happened, so the published warm contact went unused.
- The resume never contained Snowflake, dbt or Power BI - the three
  literals an ATS keyword screen would have keyed on, and a risk the
  session had explicitly recorded as "accepted, not solvable". It did
  not filter him out, so a human read the dossier and the honest
  substitution framing survived first contact. One data point; not
  enough to revise strategy on, but it is evidence against assuming
  honest omissions are fatal at the screen.

Brief covers the four questions that must not go unasked (Anforderungs-
niveau K band, design/architecture scope vs current Staff + Component
Owner level, RAMSI's Java/Spring Boot/Angular share, Kidz Care rate),
the substitution answers for each named-but-non-canonical tool, the
swissTAMP/RIS/MUD context, and the thesis boundary - methods prototype,
no operational data, no accuracy figures, PSO surveyed only.

It also asks him to decide three things before the call rather than on
camera: what he does if K lands at 130-150k, if architecture is set
elsewhere, or if RAMSI turns out to be heavily Angular. Any one can be
a no, and the level question is the same shape as the declined BKW.
