Again, there is an actual shooting war going on in Europe, which OP alluded to in their submission. I have worked with people from Ukraine in previous tech jobs. I expect some or all those people are currently doing something very different.

Here in the UK and over a single weekend my company went from holding active discussions with a few prospective clients to almost every proposal being suspended for review because of the infamous "mini-budget" a few weeks ago. If we'd been a little further along and maybe setting up new hires for any of the other projects then those jobs would instantly have disappeared too. There must be many other companies here that have been dealing with the same uncertainty and its chilling effects.

Of course people still need to go out and earn a living unless there really are more urgent things they need to do. My point is that there are plenty of reasons other than OP's qualifications or resume why the job market where they are might be much tougher than one where you can expect a 10-20% response rate just from spamming out CVs.
