Read the table top to bottom and it splits into three blocks. Rows 1 to 8 are consulting and trading, with McKinsey alone at 3.78 and everything else between 3.46 and 3.68. Rows 9 to 18 are quant shops and a few software companies where the bar sits in the low 3.4s. Rows 19 to 25 are where Big Tech and the well-known startups finally appear: Google at 3.35, Databricks 3.34, Meta 3.33. Report counts matter here. Google's 3.35 is averaged across 2,337 candidates, McKinsey's 3.78 across 1,000. The consulting number is not a small-sample fluke.
Two things stand out in that table. First, the hard loops are not the low-offer loops. A.T. Kearney is #6 on difficulty and still extends offers to 48% of candidates who report; Hudson River Trading is #11 and converts 6%. Second, the experience column runs from 12% to 72% positive. A hard interview that is well run, like Bain or Jane Street, leaves candidates feeling fine. A hard interview that is badly run, like Canonical, does not.

How this was built
Interview reports are candidate-submitted interview experiences in Dataford's pipeline (Glassdoor, Blind, LeetCode and other sources). Difficulty is 1 (very easy) to 5 (very difficult); 3 is average. Experience is the share of reports marked positive or negative. Offer rate counts only reports that were fully parsed; companies whose reports carry no offer information at all are excluded from offer rankings.
Employee ratings for work-life balance, career opportunities, management and overall are 1 to 5. Where a company has 500+ Glassdoor reviews in its aggregate profile that figure is used; otherwise Dataford's own scraped review sample (100+ reviews). Pay is the company median across tech-role pay bands: leveled total-comp ladders where published, otherwise best-supported posted ranges (15+ data points). Posted ranges understate equity-heavy packages.
Each ranking states its own threshold. Near-duplicate company names were merged and review-farm entries removed. Snapshot 4 September 2026. Built from internal data only.
