There is your problem right there, the phone is 10 years old and is only really any good for a pure phone alone, almost all apps will refuse to run on such an old platform.
That said however, I do still agree with you about the interviews, it is my firm belief that these should be conducted in person, and I also believe that the interviewer should reimburse the cost of attending such interviews. Today it is common place for some people to have been out of work for a period and therefore may not have the wherewith all to afford to attend the interview, having other greater priorities for their cash, like eating, rent etc.
In the past, I have been asked to attend interviews over 100 miles away . When I used to interview people for positions, I used to go to a hotel close to them and do the interview there, and likewise, the better companies who have interviewed me for a job, have all come to see me, either at home or in a very local hotel. But these days, such etiquette seems to be alien to most companies.
But back to your phone, it is a thorny point in my side as well about phone companies and app developers not being willing to at least ensure that their products are capable of being used to their full design capability for at least a 10-year period. Not everyone can afford to splash many hundreds of pounds on new phones every 2 to 3 years, when inflation is creeping up and up all the time and wages failing miserably to keep pace, so in essence most people today are far worse off than they were 10 years ago
EDIT
I'm in a similar position now with my phone, it is 3 years old, and some apps are already incompatible with it and the phone makers are no longer supporting it with software updates. The phone is taking longer and longer to respond to anything these days, and I don't even have a single game installed on it, has 64GB internal storage with only 28.5Gb used and also has a 64GB memory card fitted with only 288MB used, so space is not an issue. I'm already looking for another phone but don't want to spend hundreds on a phone when my income is limited to pension only.
Well the point is that even if I had the money, I would not want to renew my phone unless it's broken, because that would be encouraging hyper-consumerism and e-waste, which I hate.
I am not anti-tech, having a new phone would not make me any better at tech than using my 10 year old phone... newer one will not do more than the old one did, all it will do is have the latest OS so that apps actually accept to install on it.... Phones allow you to phone, go to the web and run XY app. Any smartphone does that. Using the latest Smartphone will not make me any worse or better at tech. Just like replacing your car every year will not make you a more skilled and knowledgeable drier than me in my 23 year old Safrane. The guy and brain holding the wheel never change.
Anyway, think I got an idea.... I don't need to use MY phone to connect to their TEAM interview, it's just a link. I can open it using any phone so... I will ask a friend or two see if they can pass me their phone Friday morning for an hour...
I did plan on upgrading my phone fairly soon I admit, because it's uselessly slow at switching between open applications (say switching from the phone app to Firefox), and Firefox / browsing is extremely slow at loading pages / running websites, it is very painful.
But, I checked and you can now get a brand new smartphone for only 50 Euros ! Might push it to 75 Euros but not more. All I want is more strage space and a faster processor, which even a 50 Euros brand new phone should I guess be able to provide, compared to my 10 year old one. So I will cough 50 Euros sometime in the next year or two, and will keep that hopefully for another 10 years. The cheaper it is, the longer you keep it, the less damaged it does to your wallet and the environment.
That why I fully intend to run my 1999 Safrane and it's 345.000kms, to the ground. Chassis has not rust, engine is strong and bullet proof, 5 cylinder N/A Mansaxel engine, it can do much more than that.
Previous car 4 years ago almost, was my Renault 21 Turbo diesel. Sold it at 450.000kms. Engine and gearbox were still working like new, was even still on its original clutch... I would still have that car today if it were not for the rust cancer which, although was not in any safety related / dangerous area, failed to pass the recently strengthened MOT. Now they are overly critical about rust. A blown head gasket and worn out shocks, they don't give a fuck, but rust that's not even putting the safety at risk... they somehow care.
OK so now let's find somebody who can pass me his more modern phone....
