He worked as an analyst for as little as, if not less, than two and a half years by the time he had received his first promotion.
A. He worked as an analyst for as little as, if not less, than two and a half years by the time he had received his first promotion
1.The sequence of events is reversed. It should be “had worked” and “received” because he first worked and then received. “by the time” requires past perfect in this context.
2. “as little as, if not less, than” is incorrect construction.
B. His work as an analyst had been for as few, if not fewer than, two and a half years by the time he received his first promotion
1. time period is uncountable, so “few” and “fewer” is incorrect.
2. “as few, if not fewer than,” incorrect construction, misses “as”, and makes no sense.
C. He had worked as an analyst for as little as two and a half years, if not less, by the time he received his first promotion
Correct choice: logical sequence of events, “as little as” makes sense with time perod.
D. He has worked as an analyst for as few as two and a half years, if not fewer, by the time he has received his first promotion
1. present perfect tense doesn’t make sense for the event that transpired in the past.
2. time period is uncountable, so “few” and “fewer” is incorrect.
E. His work as an analyst was as few as, if not fewer than, two and a half years by the time the first promotion was received by him
1. “work” is uncountable, so “few” is incorrect.
2. “was received” is a convoluted language.
3. “by the time” needs past perfect.
Hence C
