From: Priya Anand, Recruiting Lead To: Dan Voss, Engineering Hiring Manager Subject: Q2 backend-engineer funnel, where we're losing people

Dan,

Here's the Q2 picture for the backend-engineer req. We received 600 applications. Of those, 240 passed the resume screen. We invited all 240 to the online coding assessment, but only 150 actually completed it, a big drop we should talk about. Of the 150 who completed the assessment, 60 passed our cutoff and went to the technical phone screen. 36 passed the phone screen and went to the on-site loop. We extended 12 offers and 9 were accepted.

Two policy notes that may bear on the drop-off: (1) since April we require the coding assessment to be completed within 48 hours of the invitation, with no extensions; (2) we raised the assessment passing cutoff in April from the 50th to the 70th percentile.

Priya

Suppose the team eliminates the 48-hour completion window and the recovery Dan's email describes actually materializes, with every later within-stage pass rate in the table staying the same. The new completion count is not given to you; derive it from Dan's email and Priya's stage counts. On that basis, approximately how many offers would the funnel then extend?

Answer & Explanation

Correct answer

B

The new completion count must be constructed from both emails and the table. Priya's email gives: 240 invited, 150 completed, so 240 − 150 = 90 candidates were lost at the invite-to-completion stage. Dan's email supplies the recovery rate: the coordinator estimates one-third of those lost would have completed. Recovered completions = (1/3) × 90 = 30. New completion count = 150 + 30 = 180.

Applying the later within-stage pass rates from the table (unchanged): cutoff met = 40% × 180 = 72; phone-screen pass = 60% × 72 = 43.2; on-site to offer = one-third × 43.2 ≈ 14.4, which rounds to approximately 14 offers.

12 is the original offer count and ignores the recovery entirely. 15 comes from rounding 14.4 up rather than to the nearest whole number. 18 comes from over-crediting the recovery, treating the funnel as yielding more offers than the one-third estimate and the full filter chain allow. 24 applies the recovery correctly to reach 180 but then omits the 60% phone-screen filter, going 40% × 180 = 72 and then one-third of 72 = 24.
