states bound to the neighboring vortex cores. This hybridization of vortex core states can perturb the CdGM spectra of isolated vortices and the circular symmetry of the LDOS peaks (see, e.g., Ref. ). Note that the LDOS peak anisotropy may also reflect possible superconducting gap and Fermi surface anisotropy, and formation of the charge density wave order[@STSHess; @STSmore2; @IchiokaStar].

The goal of the present manuscript is to show by the example of mesoscopic superconductor that the interference of quasiparticle waves trapped in neighboring vortex cores can result even in more dramatic consequences for the LDOS profiles around the vortex configurations. These consequences are not limited just to the distortion of the LDOS peaks at individual vortex positions caused by the concrete symmetry of the system and/or vortex configuration. The peak positions themselves appear to be shifted from the superconducting phase singularity points which are usually considered as vortex centers. Changing the external magnetic field we can control the vortex configuration in the sample and switch between different Andreev interference patterns in LDOS. The distinctive features of the electronic structure of vortices in mesoscopic samples with sizes of several coherence lengths are controlled by two key factors: (i) quasiparticle tunneling between
