Interview Focus Areas

- Data structures and algorithms for coding rounds.
- System design depth for mid-to-senior roles.
- Object-oriented design or behavioral framing where applicable.
Total Compensation Breakdown
1E compensation typically combines base salary, cash bonus, and equity. The equity portion can be a large share of total compensation at mid-to-senior levels, so it is worth understanding how equity is valued and scheduled.
Median package
The median total compensation (p50) estimate is about $100,000. This median aligns with a mid-level mix of base ($100,000), bonus ($0), and equity ($0 annualized). Actual packages depend on level, location, and offer timing.
Percentile range
The p10-p90 range ($100,000 - $200,000) reflects wide variation across levels and locations. Use this range as a boundary for expectations, not a promise. Junior offers cluster toward the lower end, while senior and staff offers cluster toward the upper end.
Compensation by Location
Location is one of the biggest drivers of compensation variance. 1E adjusts compensation for geography and cost of labor.
High-cost hubs
Markets like the Bay Area, New York, and Seattle tend to land higher in the ranges. These locations also have stronger competition, so the distribution skews upward for experienced candidates.
Lower-cost markets and remote
Lower-cost locations often land toward the lower-middle of the range. Remote offers can vary by region and may include adjustments based on local salary bands.

How leveling impacts ranges
