Lancaster is currently the England Saxons coach and head of player development at the Rugby Football Union, a role which covers 95% of the performance director's job description.
The recruitment process has been put on hold until June, while the RFU conduct a review of how they have made such a mess of the appointment.
The RFU changed the job description for the performance director role twice in the space of 48 hours and Sir Clive Woodward, the preferred candidate for many at Twickenham, then ruled himself out of the running.
The bone of contention within the RFU has been whether or not the performance director should sit above the England manager in the chain of command and influence the senior international team.
Lancaster is on the RFU's shortlist and wants to continue his work, helping England prepare for the 2015 World Cup on home soil and build for the 2019 tournament and beyond.
"My role is to coach the Saxons team, run all the regional academies and run all the national age-group teams," said Lancaster.
"If you look at the job spec [for the performance director's position], it is not overly dissimilar apart from one or two quite significant parts.
"Clearly it is a role that I am currently doing and have been doing for the last three years so it is a role that I would be interested in if the opportunity came up.
"I do believe from my point of view, there is a lot of good people in the programme and lot of good things going on and we need to consider that going forward."
Lancaster will coach an England XV against the Barbarians on Sunday before leading the Saxons into next month's Churchill Cup campaign but he has a presentation ready for his interview.
"Clearly what is going on above my head, I can't influence so I am just keeping control of what I can control and continue to do the job to the best that I can. Whatever will happen in the future, will happen," he said.
"In the short term, I have four international games in four weeks as well as managing the day job, which is managing the regional academy programmes, trying to support the Under-20s, the Under-18s are going to Australia and the Sevens team are up in Edinburgh."
