Analysis

Hosuk Song is an examiner in Art Unit 2129 of Tech Center 3600. He has a very high volume of 1547 resolved cases with an allowance rate of 94.6%. The median days to allowance is 805, which is an efficient timeframe.

The interview lift is 3.0%, which is minimal. Given the 94.6% allowance rate, most applications are likely reaching allowance without the need for an interview.

The 1547 resolved cases provide an exceptionally stable data set. While the 3.0% lift is small, it indicates that interviews are at least not harmful, though they may not be necessary for most cases.
