Wayne Carlisle has overseen draws with Birmingham and Leeds and a defeat at Hull City in his three games in caretaker charge of Rotherham
Rotherham caretaker Wayne Carlisle says he did not expect to still be in charge of the Championship strugglers.
The 44-year-old Northern Irishman was assistant manager before Matt Taylor's sacking last month.
Carlisle has led the Millers to two points from their past three games.
"Your guess is as good as mine, I thought that was going to be the case with the last game," he told BBC Radio Sheffield when asked if Saturday's game with Swansea would be his final one.
"I was expecting some sort of resolution on Saturday or Sunday. This week has been particularly challenging in the fact that we have gone day-to-day.
"Some days I've been driving in not knowing if there's going to be someone [a new manager] there or not."
Former Wigan boss Leam Richardson has been linked with the vacancy at the New York Stadium.
Carlisle will come up against another caretaker in Saturday's game with the Swans, who will be led by Alan Sheehan after they sacked Michael Duff on Monday.
Duff's exit, alongside that of Sunderland boss Tony Mowbray on the same day, means that nine of the 24 Championship clubs have made a change in the dugout already this season.
"It's just another thing to chuck into the mix," Carlisle said.
"We've prepared ourselves as best we can. I think Swansea have a pretty clear identity as a club which is probably why Michael is no longer there unfortunately, as they'd drifted away from that a little bit.
"We know what kind of thing to expect and we've planned accordingly.
He added: "We've had a couple of draws so if we can get a win then we can walk out of the door knowing we've left the club in a pretty decent place.
"I'm proud of myself and the club and whatever happens this is something I'll look back fondly on."
