The Namibian-born prop, who joined Warriors ahead of the 2024 season, has settled in Scotland after a turbulent spell in England. After impressing with Cornish Pirates and Exeter Chiefs, Schickerling earned a call-up to an England training camp in 2022 under Eddie Jones and featured against the Barbarians, later being named in a 36-man squad for Australia.
However, a rule change extending residency from three to five years made him ineligible until November 2023, halting his progress.
Reflecting on the setback, he said: "It all happened really quickly. I saw someone tweeting that he's not eligible. So I kind of contacted my agent.
"We both followed all the rules of the RFU. I'm still not really sure where the mistake happened. It was really hard at the start I'd say because everything went away with one phone call before that Autumn Nations squad got announced.
"Then things didn't really go my way from then onwards. It took a while to get back on my feet. That's why I enjoy coming to Glasgow and having a fresh start and finding my feet again. I'm really enjoying my rugby at the moment again.
"Everything happened pretty quickly. I was on loan at Cornish Pirates, and played a few games at Exeter. I was fortunate enough to get the call-up. Everything happened in the space of a few months. You get on such a high and get knocked down so quickly.
"Obviously, I had a bit of time because I was still quite young. I was 23 years old. Obviously, a long way away from home. It was pretty difficult but you have to work past these things and look forward to the future because that's obviously what you can control."
Since making the move north, Schickerling has embraced a new challenge - developing his ability to operate on both sides of the scrum.
Traditionally a tighthead, the prop has added versatility to his game at Scotstoun, gaining valuable experience at loosehead.
"Obviously at the start it was a bit challenging," he admitted. "Your initial reaction is; I want to play my side, I want to make the stamp. But then you realise in the long run it benefits yourself as well because you can kind of figure out what the opposition wants to do.
"After a few games I've actually learnt a lot on that side so it's benefited me a lot. I'd say probably the angles you push and small details like that are the major differences."
There were plenty of moments in Glasgow's gritty Champions Cup last-16 win over the Bulls last weekend when Schickerling looked every inch the modern, all-action front-rower.
He made his mark early with a strong counter-ruck turnover, carried powerfully to put the hosts on the front foot, and even broke down the touchline with a clever dummy and offload. Winning a crucial penalty at the breakdown underlined how the role of a prop continues to evolve.
His second-half try - bursting onto a pass from Ben Afshar and finishing with help from Gregor Hiddleston - was a highlight, but earning a scrum penalty against Francois Klopper after early pressure may have been just as satisfying.
"I didn't have much chance to think about all the other stuff. The battle in the scrum was tough, so I was just narrowing down on trying to dominate the set-piece," he said. "That's a big strength of theirs so we always knew we had to go in front-on and fight fire with fire."
The 27-year-old admitted his 66 minute shift - his longest at senior level was "up there" among his best performances, even if head coach Franco Smith kept quiet.
"You don't really want to hear from Franco, as he will tell you if there's something wrong. But if things go well, you don't tend to hear from him, so you just keep working hard and doing what you're doing."
Now, with Glasgow pushing deep into Europe and preparing to face Toulon with a semi-final place on the line, confidence is high.
"We're aiming to play in finals and bigger things. We know what Toulon bring. It will be exciting to play at our fortress again and hopefully get the win. We are just focused on being the best we can be. We know we are on fire and if we play the way we know we can, all these things will happen if everyone does their job."
